Glass Bottle for Children "Princess" children • neoprene cover • water restructuring • programmed glass • 0.3 l
Glass Bottle for Children “Princess” (300 ml) differs from standard kids’ glass bottles mainly in the material used: it is made from patented “programmed” TPS glass, which “revitalizes” and restructures water within a few minutes. This technology is why Flaska is not just an “ordinary” glass bottle and why its price differs from typical bottles.
The pink neoprene sleeve with a princess motif makes the bottle easier to grip, feels comfortable for children to hold, and is replaceable and washable (recommended up to 40 °C). With a capacity of 0.3 L, the bottle is a great option for kids for school or for trips. The bottle is not suitable for the dishwasher.
Glass Bottle for Children "Princess" – Flaska
Glass water bottle for kids made from European glass, suitable for everyday use at school and on trips as a glass alternative to plastic bottles. The manufacturer states that the bottle uses programmed glass (TPS), which is said to “revitalise” and “re-structure” the water within a few minutes – this technology, according to the brand, makes Flaska more than an ordinary glass bottle and partly explains the price difference compared with typical children’s bottles.
European glass is chemically stable and naturally free from bisphenol A; it does not absorb odors or flavors. Bisphenol A (BPA) is a synthetic substance used in some plastics; it can migrate into beverages and is associated with hormonal activity, which is why it is regulated in the EU.
The reusable design helps reduce single-use plastic bottles. A leak-proof cap and a neoprene sleeve that can be removed and washed make this bottle a reliable choice for a backpack and after-school activities.

How are Flaska bottles different from “ordinary” bottles?
Compared to plastic bottles, Flaska offers the benefits of glass: it is chemically stable, so it does not retain odors or flavors and does not absorb colorants from beverages.
Glass is also naturally BPA-free and contains no plasticizers, while plastic can, over time, pick up smells or release components into the drink.
From a hygiene perspective, glass is easy to clean and tolerates hot water and thorough mechanical cleaning with a brush, without a film forming on the surface. Plastic, on the other hand, scratches more easily, and micro-scratches can reduce washability and make it harder to keep clean.
Over its life cycle, a glass bottle, when handled gently, has a long lifespan and is fully recyclable, which reduces the need for single-use packaging. Plastic may be lighter, but it usually has a shorter usable life and keeps beverage taste neutrality less reliably over time.
In practice, glass is heavier and more fragile, but Flaska balances this with accessories. You can choose cork or neoprene sleeves and bottles in several sizes, making it easy to find a version for work, sport, travel, and home serving.

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 great for sport and free time – for fitness, yoga, hiking, and cycling. Flaska also offers bottles for children to help support a regular drinking routine at school and after-school activities.
They are practical for travel and daily commuting – in a backpack or car, on a trip, and around the city. You can easily refill the bottle at water fountains or at home before you leave, so you always have water within reach.
Flaska bottles come in various 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 colors and motifs for children and adults. The sleeve improves grip and completes the look of the bottle; neoprene sleeves are also removable and washable, while cork and silicone sleeves can be easily removed and wiped clean with a damp cloth.
Why choose Flaska
Flaska bottles are reusable glass bottles that keep water taste-neutral and free from unwanted odors. Glass is inert and naturally BPA-free, so it does not react with the drink and does not release anything into it.
Part of the brand’s identity is also the approach the manufacturer calls “programmed glass” – their own way of focusing on quality and the experience of water.
Flaska bottles fit easily into everyday hydration at work, at home, while studying, and on the go. Thanks to a comfortable neck and a quality cap, they are easy to clean and pleasant to drink from.
The brand offers several bottle sizes and different design variants with a cork, neoprene, or silicone sleeve. Sleeves improve grip and complete the look of the bottle; neoprene sleeves are also removable and washable, while cork and silicone sleeves can be easily removed and cleaned.
For a long lifespan, hand washing with a mild detergent and regular airing of the lid is recommended. Reusing a glass bottle helps reduce single-use plastic packaging.

FAQ
What is the Glass & Vibe technology and how should the bottle be used?
The manufacturer states that the glass contains a vibrational program intended to “tune” the water in about 5 minutes. Steps: fill the bottle, wait, gently swirl the water, and drink. Please treat this as a brand claim, not a health effect.

Is Flaska BPA-free and what materials is it made from?
Yes. Glass is naturally BPA-free, contains no plasticizers, and is inert (it does not react with the drink). Accessories mainly include cork and neoprene sleeves for protection and comfortable carrying.

Can I wash the bottle in a dishwasher?
Not recommended. Care is hand washing only – use a soft brush and a mild detergent. This helps the bottle and sleeve keep a longer lifespan.

What about hot water – can I pour hot drinks into the bottle?
Hot drinks may reduce the declared “structuring” effect. Recommendation: prepare the hot drink separately and let it cool, or use special cups/glasses intended for hot drinks (the “tuning” information is a manufacturer claim).

How durable is the bottle and what should I avoid?
Glass is robust, but it remains a fragile material. We recommend using a protective sleeve, avoiding drops and impacts, not using it in a 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. Available options include replaceable sleeves (cork, neoprene), replacement lids, and other accessories for everyday use.

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.
