Q1: Is this tumbler made of food-grade material?

A: This tumbler has a 750ml capacity, providing ample hydration for daily use.

Q3: How long does the vacuum insulation keep my drink hot or cold?
A: The double-wall vacuum insulation helps maintain temperature for several hours. For best results, we recommend preheating or pre-chilling the tumbler with hot or cold water for a few minutes before filling.

A: The wide mouth design makes it easy to add ice cubes, fill the tumbler, and clean the interior thoroughly.

Before First Use:
Wash the tumbler, lid, and silicone gasket with warm soapy water and rinse thoroughly. Do not use abrasive cleaners or metal scouring pads, as they may scratch the stainless steel surface.

Daily Use Tips:
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. The wide mouth design makes it easy to add ice cubes. Do not fill completely to the brim. Leave some space at the top to prevent pressure buildup and make lid closing easier.

Cleaning Instructions:
Hand wash with a soft sponge and mild dish soap after each use. The wide mouth allows for easy access to the interior for thorough cleaning. For stubborn stains, use a mixture of baking soda and warm water, soak for 15 minutes, then rinse thoroughly. The lid and silicone gasket can be removed for thorough cleaning. Ensure the gasket is completely dry before reattaching. Avoid using bleach, chlorine-based cleaners, or abrasive pads.

Important Precautions:
Do not microwave or place in oven, stovetop, or freezer. Do not overfill with hot liquids, as steam pressure may cause the lid to pop open or leak. Avoid dropping the tumbler or subjecting it to strong impacts, as this may damage the vacuum insulation. Do not use the tumbler to store acidic or corrosive chemicals. It is designed for beverages only. 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. Close it firmly but gently to avoid damaging the threads or silicone gasket.
