How to use

Fill the travel mug with your preferred hot or cold beverage up to the recommended fill level to avoid overflow when closing the lid.

When drinking, open the closure as intended by the lid design and close it between sips to maintain temperature and prevent spills. Allow the mug to cool before opening after holding very hot liquids.

Usage recommendations

Hand wash recommended for the lid to preserve seals and mechanisms; the insulated body may be rinsed or hand-washed according to care instructions. Avoid using abrasive cleaners or scouring pads on the outer coating. Do not place the travel mug in a microwave. For optimal thermal performance, preheat or precool the mug by rinsing with hot or cold water before pouring your beverage.
