FAQs about FLSK.
Inspired by the Scandinavian design style, the FLSK team has designed a minimalist, purist drinking bottle. FLSK is pronounced "flask" ([flɑːsk]) and is the English word for "bottle".
What's really special about the FLSK is its insulating performance. It keeps your drink ice cold for 24 hours and hot for 18 hours. So when you step out of the house in the morning on a warm summer day, you don't have to worry at all about your drink getting warm and then not tasting good. It's the same in winter: If you have a hot drink with you, you can warm up on it all day long.
No matter where you buy the FLSK - you always get it in a high-quality tube box packaging. This protects against scratches and looks so good that you can give the FLSK directly as a gift.
The FLSK is the revolution of the conventional drinking bottle - simple from the outside, but ultra functional from the inside. It is made of pure stainless steel, so it is completely rustproof, odorless and tasteless.
For you, this means: You can fill it with anything you like. Whether it's tea, maybe a beer, sparkling mineral water or even champagne.
To enjoy the perfect FLSK moment at any time, it's best to follow these tips and tricks.
The FLSK water bottle is available in nine colors and four sizes. If you're still not sure which FLSK you like best, you can check them out live in one of the over 800 stores in Germany, Austria and Switzerland.

It is better not to clean the FLSK in the dishwasher. Due to its conical shape, hardly any water gets inside the bottle, and the paint can also be damaged.
The daily cleaning of the FLSK is nevertheless very simple. Unlike conventional thermo bottles it contains no glass inside that could break and is therefore much more robust. The FLSK stainless steel drinking bottle can be conveniently rinsed with boiling hot water and a little dishwashing liquid. Regular cleaning is important here, so that substances such as teein or caffeine cannot settle in the first place. If something does get deposited, our cleaning balls or a commercial denture cleaner from the drugstore will help.

VICC® stands for Vacuum Insulated Copper Coating. The FLSK drinking bottle combines unique design with high functionality. It is made of stainless steel and maintains the temperature through the VICC® technology longer than other thermo bottles. Between the double-walled stainless steel is a vacuum layer, and in addition a copper coating guarantees the preservation of the temperature. Due to the narrow opening and the double-insulated lid, the FLSK drinking bottles are 100 % leak-proof.

The FLSK thermo bottle is also very suitable for children. The small size with 350 ml capacity is very light and small and therefore suitable for children's hands. When preparing baby food, hot boiled water can be filled into the FLSK stainless steel drinking bottle to always be able to prepare baby milk during outings. It is therefore ideal in its function as a baby insulated bottle. For toddlers, fruit spritzer or juice can be transported in the FLSK thermo bottle for kindergarten. Also at school, the FLSK drinking bottle becomes a companion. The older ones can then also take a larger bottle - after all, a balanced drinking pattern is more than important for the development of the little ones!

FAQs about the Movement.
18/8 means that the stainless steel contains 18% chromium and 8% nickel. Both are alloying elements that make the stainless steel resistant to corrosion and acid. This means that our products are guaranteed rust-free. The plastic components of our products are polypropylene (PP), polystyrene (EPS) and movable silicone in the sealing rings. These are necessary to ensure the insulating and sealing function in the lid of the FLSK and the TriZone ThermoGuard of the muki.
Both products are BPA free in their entire material composition, contain no plasticizers and are thus completely free of harmful substances. This makes them the perfect reusable alternative to plastic products.
FAQs about muki.
Congratulations, you have made an excellent choice and have chosen the muki as a snack pot that will accompany you every day.
The best way to clean your muki snack pot is with lukewarm water, a dishwashing sponge and some detergent. Be careful with color intensive food like berries or similar: You should first rinse the TriZone ThermoGuard with cold water to prevent discoloration. Both sealing rings and the pressure valve can be removed and cleaned individually.
To avoid odors or discoloration, you should clean and dry your muki after each use. We recommend not to put the muki in the dishwasher, otherwise the powder coating could be damaged.

FAQs about the additionals.
There is currently no neoprene bag for the FLSK 350 ml. However, the small FLSK fits perfectly into the FLSK neoprene bag 500 ml, where it is protected from scratches and shocks.
In every new FLSK drinking bottle there is a spare sealing ring to change. If you need a new sealing ring, please write a mail to hallo@flsk.de.
