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".

It is better not to clean the FLSK in the dishwasher. Due to its conical shape, hardly any water gets into the bottle, and the color coating can be damaged. 

Daily cleaning of the FLSK is still very easy. In contrast to conventional thermo bottles it does not contain any glass inside that could break and is therefore much more robust. The FLSK stainless steel drinking bottle can be easily rinsed with boiling hot water and a little washing-up liquid. It is important to clean it regularly, so that substances such as teaine or caffeine do not settle at all. In the case of settled sediments, our cleaning balls or a standard denture cleaner from the drugstore will help. 

Here you can find detailed information on cleaning your FLSK drinking bottle.

We are sorry if your favorite FLSK is sold out in our online shop - your favorite is very much in demand, you must have a very good taste! Of course we will try to replenish as soon as possible and offer the full selection in our shop. In the product description in the online shop you will find the exact date when your favorite will be available again. And of course we will announce this in our newsletter.

Sustainability and ecological harmlessness play an increasingly important role in the product world today. The FLSK as an innovative drinking bottle is therefore made of 100 % type 304 stainless steel, completely BPA-free and contains no plasticizers. As a pollutant-free drinking bottle, it is a healthy alternative to conventional plastic bottles. In addition to high product quality, we at FLSK also pay close attention to non-profit making and a fair production chain. 

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 longer than other insulated bottles thanks to VICC® technology. Between the double-walled stainless steel there is a vacuum layer, additionally a copper coating guarantees that the temperature is maintained. Due to the narrow opening and the double insulated lid, the FLSK water bottle is 100% leak-proof. Learn more about the new technology of the FLSK stainless steel drinking bottle here!

The FLSK drinking 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 poured into the FLSK stainless steel drinking bottle, so that baby milk can always be prepared on the go. It is therefore ideal in its function as a baby vacuum flask. For small children, fruit spritzer or juice can be transported in the FLSK drinking bottle for kindergarten. The FLSK drinking bottle also becomes a companion at school. Older children can also take a larger bottle with them - after all, a balanced drinking pattern is more than important for the development of the little ones!

Yes, in the FLSK Online Shop you can give your FLSK a very individual touch with a personal engraving. All information about engraving at a glance can be found here.

Congratulations, you have made an excellent choice and with the muki you have chosen a snack pot that will accompany you daily.  

We've prepared detailed instructions and lots of tips for you to enjoy your perfect muki moment every time.

The best way to clean your muki snack pot is to use lukewarm water, a dishwashing sponge and some dishwashing liquid. A little caution is advised with color-intensive food like berries etc.: The TriZone ThermoGuard should first be rinsed with cold water to prevent discoloration. Both sealing rings and the pressure valve can be removed and cleaned separately.

The muki snack pot can be personalized in the online shop with a laser engraving. This is especially helpful when every family member has their own muki, so nothing gets mixed up in the kitchen. An engraved muki is also a very special, personal gift.

There is currently no neoprene bag available for the FLSK 350 ml. But the small FLSK also fits perfectly into the FLSK neoprene bag 500 ml, where it is completely protected from scratches and shocks.

In every new FLSK drinking bottle there is a spare sealing ring for replacement. If you need a new sealing ring, please send an e-mail to hallo@flsk.de.

The FLSK drinking bottles in the sizes 500 ml, 750 ml and 1000 ml can be ordered as a package with a matching neoprene bag and the cleaning beads. You save 9,50 € compared to the single purchase. 
This is not possible with the FLSK drinking bottles in the 350 ml size, because there is no neoprene bag in this size (yet).
