Two kinds of mug made from Japanese cedar or Hinoki (Japanese cypress) with a beautiful and refined wood grain. It has a unique design, in which the body and handle form one piece. Its name derives from the fact that when looking straight down at the cup from above it looks like the letter "α“(alpha). It has the dual functionality of both being light due to being wooden, and retaining heat well. The bottom section is airtight and coated with ceramic, so coffee, tea and other hot drinks can be drunk without problems.
