Q2: Is the tumbler dishwasher safe?
A: The stainless steel body is dishwasher safe, but we recommend hand washing the lid to prolong its lifespan, as high-temperature dishwasher cycles may warp plastic components.

Q3: Can I put the tumbler in the microwave?
A: No. The stainless steel material is not microwave-safe. Do not place it in a microwave, oven, or on a stovetop.

Q4: Is the lid leakproof?

A: The wide mouth design makes it easy to add ice cubes, fruit, or tea bags, and allows for effortless hand cleaning. It also makes filling and drinking more convenient.

A: Yes, but we recommend leaving some space at the top and opening the lid slowly to release pressure, especially after shaking or when the drink is warm.

Q7: How should I clean the tumbler?

The wide mouth design makes it easy to add ice cubes, fruit slices, or tea bags. For hot drinks, preheat the tumbler with hot water for a few minutes, then empty and fill with your beverage. For cold drinks, pre-chill the tumbler with cold water, then empty and fill. Do not fill completely to the brim. Leave some space at the top to prevent pressure buildup and make lid closing easier.

Ensure the gasket is completely dry before reattaching. Avoid using bleach, chlorine-based cleaners, or abrasive pads.

When not in use for extended periods, store the tumbler with the lid removed to allow air circulation and prevent odors. Do not overtighten the lid.
