This is a wooden beer mug made of Japanese cypress (hinoki), designed to be drunk from a masu (a wooden square cup). It has excellent heat retention. This is a square-shaped mug, not round. I bought it as a souvenir and have never used it, keeping it in storage. It's a new, unused, and beautiful item, so I hope you'll consider it. I will pack and ship it in a plain case. The dimensions are 14x14x10 cm.
