Thank you for viewing. This is a wooden masu (square wooden cup) sold at a marasy live. It features a piano motif logo on the side and a branding of a monkey on the bottom, making it a live merchandise from that time. I've forgotten the specific live name, but I believe it was live merchandise from around the time marasy started doing more drinking streams with sake. 【Condition】 ・It's in very beautiful condition because it was stored in a box. ・The box was so tight that it got a crease when I took it out and put it back in for the photos. Thank you very much.
