Thermos mug with Rauma City of the Sea logo

The 2 in 1 steel thermos flask keeps your drink hot or cold for a long time, depending on your needs.

The Coolermuk can be fitted with a 330ml beverage can (narrower model). Thanks to the silicone seal, the can stays in the cooler until you're ready to take it out.

Replace the can ring with the plastic lid and the mug turns from a cooler into a thermos mug. The mug is designed with an ergonomic handle and also fits in a car mug holder.
