Regatta Thermulate Insulated Mug - 1.2L - Yellow

No, hand washing is recommended to maintain the integrity of the insulation and the mug's finish.

The interior is made of 304 stainless steel for optimal performance and durability.

It can keep drinks cold for up to 12 hours.

It can keep drinks hot for up to 6 hours.

While the mug can hold carbonated beverages, opening the flip-top straw lid may cause excessive foaming or pressure release. It is generally best used for non-carbonated drinks.

The lid is leak-proof, but it does not have a separate safety lock. The flip-top mechanism must be manually closed to ensure it is sealed.

The mug has a total capacity of 1.2 liters.

Ensure the lid is screwed on tightly. Pre-condition the mug by filling it with hot water for hot drinks or cold water for cold drinks for a few minutes before filling with your beverage. Check that the lid seal is intact and not damaged.

Disassemble the lid and clean the straw thoroughly. Check for any debris or residue blocking the straw. Ensure the straw is correctly inserted into the lid mechanism.

Wash the mug and lid thoroughly with warm, soapy water. For stubborn odors, try filling the mug with a mixture of baking soda and water and letting it sit overnight before washing. Ensure the mug is completely dry when stored.

This is uncommon with double-wall insulation. If you notice significant temperature transfer, there may be an issue with the vacuum seal. Contact customer support if the problem persists.
