Regatta Cath Kidston Thermulate Mug - 1200ml - Green

The mug keeps drinks hot for up to 6 hours and cold for up to 12 hours.

The mug is constructed from durable stainless steel with a double-walled design.

No, this mug is hand wash only to preserve its insulation and exterior finish.

The mug has a capacity of 1.2 litres (1200ml).

Yes, the mug features a twist lid with an integrated straw for convenient sipping.

While the lid is designed to be secure, it is generally best to use this insulated tumbler for non-carbonated beverages to maintain optimal performance and prevent potential pressure buildup.

No, this stainless steel mug should never be placed in a microwave.

Ensure the lid is tightly sealed and the twist mechanism is fully engaged. Pre-warm the mug with hot water or pre-chill with cold water for a few minutes before filling for optimal temperature retention. Check for any damage to the double-walled insulation.

Ensure no dried liquid is around the sealing areas. Rinse the lid and threads under warm water. Check for any debris caught in the threads. Do not force the lid; if persistent, contact customer support.

Disassemble the lid components if possible and clean the straw thoroughly with a small brush. Ensure no ice or large pieces of fruit are obstructing the flow.

This usually indicates a compromised vacuum seal in the double-walled construction, meaning the insulation is no longer effective. Ensure the lid is properly sealed. If the issue persists, the insulation may be damaged.
