When you received the tumbler, the handle was not installed. However, you can easily self-install it using the free screwdriver and accessories provided.

To drink water, use a straw, but ensure the water temperature is less than 60°C to avoid burns. Refrain from aligning the human body when switching, as this can also lead to burns.

It is strictly prohibited to place the products in a bright fire, microwave oven, induction cooker, or dishwasher. Additionally, do not add dried ice, carbonated beverages, soy sauce, soup, or any liquid containing alkaline or acidic ingredients, as these can corrode the cup body.

For cleaning, use a neutral detergent and water. Avoid using alkaline bleach, chemical cloths, or any other cleaning agents.
