Does Flaska require special maintenance? E.g. eco wash balls have to be placed in the sun to be recharged.

The information is inscribed into the glass's silicon and protected by a special symbol. Special maintenance (or "recharging") is therefore not needed, but it is recommended that you avoid strong radiation sources, such as microwave ovens.


Usage nearby computers or mobile phones is not problematic. Flaska can also be placed next to the induction panel.
