The unique coasters that made with aluminum were created by metal spinning technique. They are just the right size to use with any glass, and to be used as a tray to put small items such as keys, jewelry, coins etc.
We have Natural Silver color and Kuro-Mura Black color available.
Kuro-Mura black finish is a traditional method used for Buddhist altar articles, which mixes pigments with Japanese lacquer, URUSHI.
The coaster's aluminum gradually changes color over time due to oxidization. The longer it is used, the richer and subtler it becomes.
