When using the tumbler, please be cautious: use a straw to drink water, and ensure the water temperature is less than 60°C to avoid burns. It is strictly forbidden to place the products in bright fire, microwave ovens, induction cookers, or dishwashers.

Additionally, do not add dried ice, carbonated beverages, soy sauce, soup, or liquids containing alkaline and acidic ingredients to the cup, as this can cause corrosion of the cup body. When cleaning, use a neutral detergent and water. Avoid using alkaline bleach, chemical cloths, or other cleaning agents.

Their double-wall vacuum insulation keeps drinks at the perfect temperature, while the cupholder-friendly design and portable features make them ideal for everyday use and gift-giving occasions.
