Gamer Design Tumbler - Multicolor - 850ml

The tumbler is constructed from durable materials suitable for everyday use, designed to be safe for hot and cold beverages.

While the tumbler can hold carbonated beverages, it is not specifically designed as a carbonation-retaining flask. Opening the lid may release pressure.

The lid is designed to be secure to minimize leaks when closed properly. However, it is not guaranteed to be completely leak-proof, especially if tipped over forcefully or packed loosely in a bag.

The lid mechanism can be cleaned with a small brush or cotton swab dipped in warm, soapy water. Ensure all parts are rinsed thoroughly and dried completely.

Please refer to the product packaging or retailer's information for specific warranty details, as these can vary.

Yes, the tumbler is suitable for milk and other beverages. Prompt cleaning after use is recommended, especially for dairy products.

Ensure the lid is tightly sealed. Check for any damage to the twin-wall insulation, though this is uncommon. Allow the tumbler to sit empty for a few minutes before filling to acclimate.

Ensure there is no dried beverage residue around the threads or seal. Gently twist and pull or push the lid. If it remains stiff, try washing with warm soapy water and drying thoroughly.

This can occur in humid environments. While the insulation is effective internally, some condensation on the outside may happen. Ensure the exterior is wiped dry.

Ensure the lid's adjustable mechanism is correctly set to the desired drinking position. Check that the straw (if applicable) is fully inserted and not blocked.
