- Do Not Use: Avoid using abrasive cleaners, bleach, or scrubbers that could scratch the stainless steel finish. Do not place in a microwave, freezer, or conventional oven.

Troubleshooting
Lid Difficult to Open or Close:
If you find the lid difficult to open or close, especially after filling with hot beverages, it may be due to pressure changes inside the tumbler caused by thermal expansion or contraction.
Solution:
- First, open the black flip cap on the lid to release any built-up air pressure.
- Alternatively, wait a short period for the internal temperature and pressure to stabilize before attempting to close or open the lid.
Safety Information
- Hot Beverages: Exercise caution when handling hot beverages to prevent burns. The exterior of the tumbler will remain cool, but the contents will be hot.
- Not Leak-Proof: This tumbler is designed as a non-sealed cup for use in car cup holders or on flat surfaces. It is not intended to be carried horizontally in a bag or while walking, as it may leak. Always keep the tumbler upright when transporting in a bag.
- Children: Keep out of reach of small children, especially when containing hot liquids.
- Materials: The tumbler is made from food-grade 18/8 stainless steel and a BPA-free lid, ensuring safety for food contact.
