Created in a kiln at a temperature of 1055℃, this double wall tumbler has a silky smooth surface, and an unique finish that can also hide fingerprints on the surface.

Our new double walled tumblers have amazing thermal performance. After 3 hours in a 20℃ room, ice in a glass cup would completely melt, whereas in our new tumbler, over half of the ice still remains.

Kamazukuri tumblers possess natural unevenness like hand-throw pottery. And each tumbler has their own unique pattern and a silky finish.
