Care & Safety

Hand wash only with a soft sponge and mild detergent to maintain the integrity of the ceramic liner.

Handle with care: avoid dropping or subjecting the tumbler to heavy impact, as the internal ceramic layer may crack.

Ensure the lid is properly threaded before placing the bottle in a bag to prevent leakage.
