Glass Water Bottle 'Dandelion' neoprene cover • water structuring • programmed glass • 0.5 l
FLASKA Glass Water Bottle with Dandelion design (0.5 l) is not an ordinary glass bottle. The key difference lies in the material: it is made from Slovenian FLASKA glass with patented TPS technology, which according to the manufacturer, “revitalises” water in just a few minutes.
In practice, people most often describe a smoother and more balanced taste even with regular tap water – and this is the main reason why FLASKA is priced differently from standard glass bottles. The bottle features a wide neck, a screw-on wooden cap, and a removable neoprene cover with a Dandelion design, which can be washable at 40 °C. The bottle is not dishwasher safe; gentle hand washing is ideal.
Glass Water Bottle 'Dandelion' – FLASKA
Glass Water Bottle 'Dandelion' by FLASKA (0.5 l) is not an ordinary glass bottle. It is made from FLASKA’s patented “programmed” glass with Glass & Vibe technology, which, according to the manufacturer, is designed to “revitalise” and “structure” the water within a few minutes.
This specific glass and the manufacturer-described effect on the water are the main reason for the higher price, so it is not only about the appearance.
The bottle is naturally BPA free, because the water stays in glass at all times. BPA (bisphenol A) is a substance used in some plastics and, under certain conditions, can migrate from packaging into drinks.
The bottle has a screw-on wooden cap and a removable neoprene sleeve with the Dandelion motif. The sleeve can be washed at 40 °C.
The manufacturer recommends handwashing and does not recommend dishwasher cleaning; for washing, a gentle sponge and a mild washing-up liquid are suitable to help preserve the glass quality and its “programming” over time.

On pravebio.cz you will find a range of glass bottles from Flaska with different motifs and coloured sleeves – for children for example the “Frog”, and as a unisex option for both children and adults the “Lotus” bottle.
How do FLASKA bottles differ from “ordinary” bottles?
Compared to plastic bottles, Flaska brings the advantages of glass: it is chemically stable, so it does not retain odours or flavours and does not absorb colourants from drinks.
Glass is also naturally BPA free and free from plasticisers, whereas plastic can, over time, take on smells or release substances into the drink.
From a hygiene point of view, glass is easy to clean and tolerates hot water well. Plastic, on the other hand, is more easily scratched, and micro-cracks can make cleaning more difficult and affect long-term cleanliness.
Over its lifecycle, a glass bottle, when handled with care, has a long service life and is fully recyclable, which reduces the need for single-use packaging.
In practice, glass is heavier and more fragile, but Flaska balances this with accessories. There are cork and neoprene sleeves and bottles in several sizes, so you can easily choose a version for work, sport, travelling or serving drinks at home.

Who are FLASKA bottles for and where can you use them?
Flaska bottles are suitable for everyday hydration at home, in the office, at school and in meetings. They work very well for sports and leisure time – for fitness, yoga, hiking or cycling. Flaska also offers bottles for children to support a regular drinking routine at school and during after-school activities.
They are practical for travel and daily commuting – in a backpack or car, on a trip or into town. You can easily refill the bottle at public fountains or at home before you leave, so you always have water at hand.
Flaska bottles come in different designs with an integrated sleeve, so you can choose a style that matches your taste and preferences. Options include cork, neoprene and silicone sleeves in a variety of colours and motifs for children and adults.
The sleeve improves the grip and completes the look of the bottle; neoprene sleeves are also removable and washable, while cork and silicone sleeves can easily be removed and wiped clean with a damp cloth.
Why choose FLASKA
Flaska bottles are reusable glass bottles that keep water neutral in taste and free from unwanted odours. Glass is inert and naturally BPA free, so it does not react with the drink and does not release substances into it.
A key part of the brand’s identity is its approach referred to by the manufacturer as “programmed glass” – its own way of paying attention to water quality and how we perceive water.
Flaska bottles are easy to integrate into your daily hydration at work, at home, while studying or when travelling. Thanks to the comfortable neck and quality cap, they are easy to clean and pleasant to drink from.
The brand offers several bottle sizes and different design variants with cork, neoprene or silicone sleeves. The sleeves improve the grip and complete the look of the bottle; neoprene sleeves are also removable and washable, while cork and silicone sleeves can easily be removed and wiped clean.
For a long service life, handwashing with a mild detergent and regularly airing the cap are recommended. Reusing a glass bottle helps to reduce the number of single-use plastic containers.
Clean taste
A glass bottle is inert – it does not react with the drink, does not absorb odours or flavours and does not become stained by drinks.
BPA free and no plasticisers
Glass is naturally BPA free and free from plasticisers, so you avoid the typical migration of substances from plastic into your drink.
Sustainable choice
A reusable bottle with a long lifespan and a fully recyclable material reduces the number of single-use containers.
Comfort with accessories
Many bottles feature a cork sleeve for a more secure grip, while other variants come with a neoprene sleeve and additional practical elements.
Easy care
Glass is easy to wash and tolerates hot water well; when washed by hand, aromas or colourants do not build up inside the bottle.
Versatile use
For the office, school, sports, travel or serving at home – water is always close by and tastes the same.
Materials and workmanship
Glass Water Bottle 'Dandelion' by Flaska 0.5 l is made from European programmed glass (TPS/Glass & Vibe), which is chemically stable and naturally BPA free and free from other plasticisers. Glass does not absorb odours or flavours and is suitable for water throughout the day.
The screw-on wooden cap allows you to close the bottle securely and carry it in a bag or backpack (bearing in mind that it is glass). The neoprene sleeve with the Dandelion motif improves the grip (non-slip in the hand) and is removable; it can be washed at up to 40 °C. All parts intended to come into contact with water meet common food-contact requirements.
To preserve quality and function, we recommend handwashing and avoiding the dishwasher, microwave and sudden temperature shocks.
Use and care
- Before first use, rinse the bottle, cap and neoprene sleeve with warm water and a mild detergent, then allow them to dry thoroughly.
- Fill the bottle with tap or filtered water, close it with the screw-on cap and leave it for about 5 minutes to “work”.
- Wash the bottle by hand only using a soft sponge and a gentle washing-up liquid to help maintain the glass quality and its “programming” over time.
- Do not use a dishwasher; avoid the microwave and sudden temperature changes (do not pour in boiling water, do not freeze the bottle).
- Remove limescale deposits with vinegar or baking soda and then rinse the bottle thoroughly.
- The neoprene sleeve is replaceable and can be washed at 40 °C; let it dry completely before putting it back on.

FAQ
What is Glass & Vibe technology and how should I use the bottle?
The manufacturer states that a vibrational programme is imprinted into the glass, which is meant to “tune” the water within about 5 minutes. How to use it: fill the bottle, wait, gently swirl the water and then drink. Treat this principle as a brand claim, not as a health effect.

Is FLASKA BPA free and what materials is it made from?
Yes. Glass is naturally BPA free and free from plasticisers, and it is inert (it does not react with the drink). The accessories are mainly cork and neoprene sleeves.

Can I wash my FLASKA bottle in the dishwasher?
This is not recommended. Care is by hand – use a soft sponge and a mild detergent to help preserve the glass quality and its “programming” over time.

What about hot water – can I pour hot drinks into the bottle?
Hot drinks may reduce the declared “structuring” effect. The recommendation is to prepare hot drinks separately and allow them to cool, or to use dedicated cups/glasses intended for hot beverages (the information about “tuning the water” is a manufacturer claim).

How durable is the bottle and what should I avoid?
Glass is robust, but it is still a fragile material. We recommend avoiding drops and impacts, not using it in the microwave and not exposing it to extreme temperature shocks.

What sizes and accessories are available?
The brand offers several bottle sizes and a wide range of accessories. There are interchangeable sleeves (cork, neoprene), replacement caps and other everyday accessories.

Zakladatel slovinské značky Flaska, Maks Vrečko, je skutečný inovátor. Na nápad, který za Flaskou stojí, přišel při pěstování jahod. Pomáhal totiž manželce na jejich rodinné farmě. Protože ho typické zemědělství nezajímalo a klasické zemědělské technologie moc neznal, začal se zajímat o různé netradiční přístupy. V roce 2003 se díky tomu seznámil s procesem restrukturalizace vody. Rozhodl se provést vlastní pokus - polovinu pole zaléval restrukturalizovanou vodou a druhou polovinu normální vodou.
Nějakou dobu nebyly patrné žádné výrazné rozdíly, ale když nastal čas sklizně, rychle se ukázalo, že voda hrála důležitou roli. Jahody zalévané restrukturalizovanou vodou byly znatelně pevnější. Trvanlivost plodů se prodloužila a úroda na části pole, která byla zalévaná restrukturalizovanou vodou, byla o 18,1 % vydatnější. Na konci sezóny byly rostliny v této části výsadby vitálnější a méně napadené chorobami.
V následujících letech pak Maks v experimentech s restrukturalizovanou vodou pokračoval. Ze skeptika se stal nadšencem této technologie, která je známá již téměř 90 let, od objevů Viktora Schaubergera, průkopníka strukturování vody. Maks říká, že když nad tím zpětně přemýšlí, mělo to být naprosto logické, že zlepšení struktury vody povede i ke zlepšení jahod, vzhledem k tomu, že 89 % plodu jahod je tvořeno vodou. V té době ho to prý ale vůbec nenapadlo.
K údivu mnohých Maks v roce 2009 přestal pěstovat jahody. Měly vynikající kvalitu, odbyt byl skvělý a všichni byli spokojeni. Ale život mu říkal, že se musí poohlédnout po nových výzvách. Začal nabízet technologii strukturování vody v zemědělství. Přes vynikající výsledky testů (při pěstování ovoce, zeleniny, výrobě mléka, chovu drůbeže atd.) nebyl trh ještě připraven přijmout "neviditelnou" technologii, přestože její výsledky byly zcela zřejmé.
Po náročném roce a půl dostal nápad implementovat technologii strukturování vody do lahve pro každodenní použití. V listopadu 2009 byla spuštěna testovací série a po kladném ohlasu byla zahájena skutečná výroba. A tak se zrodila - Flaska! Na slovinský trh vstoupila 10. března 2010.
Věci se začaly hýbat kupředu rychlostí blesku - tým Flasky se rozrůstal, a brzy uváděli na trh nové modely a velikosti lahví a expandovali na nové světové trhy. Vypadá to jako pohádka, ale v reálném životě Flasku také čekaly těžké časy, zejména v letech 2012 až 2014. Toto období překonali jen díky společné práci a spoustě pozitivní energie všech zaměstnanců a partnerů. V následujících letech pak vyvinuli další naprogramované výrobky - džbán Vodan, Doggy Flasku pro psy a sklenici na pití Sirius.
Flaska nadále zdokonaluje proces restrukturalizace vody TPS. Jejich filozofie restrukturalizace vody se liší od většiny ostatních, které tuto technologii nabízejí. Pomáhají vodě vrátit se k její pramenité struktuře. Společnost Flaska zastává názor, že všichni obyvatelé naší planety by měli pít vodu co nejlepší kvality. Výrobou Flasky tak nejen zvyšují obecné povědomí o pití kvalitní vody, ale přispívají ke snižování vytváření plastového odpadu jednorázovými plastovými lahvemi.
Flaska je důkazem toho, že máme moc měnit svět prakticky každým douškem vody, kapku po kapce.
