When you receive the tumbler, the handle may not be pre-installed. However, free screwdrivers and accessories are provided for easy self-installation.

When using the tumbler to drink water, ensure the temperature is less than 60°C to avoid burns. It is crucial to avoid aligning the human body when switching between hot and cold contents, as this can also lead to burns.

Strictly refrain from placing the tumbler near open flames, in microwave ovens, induction cookers, or dishwashers. These environments can damage the product.

Do not add dried ice, carbonated beverages, soy sauce, soup, or any liquids containing alkaline or acidic ingredients, as these can corrode the tumbler's body.

When cleaning the tumbler, use a neutral detergent and water. Avoid using alkaline bleach, chemical cloths, or other harsh cleaning agents, as these may compromise the tumbler's integrity.
