I had something that was not for sale in Asahikawa ordered and sold to me. It's a wooden frame made by Mu Kobo, crafted from wood with a beautiful grain (possibly keyaki/Japanese zelkova). The cover is glass, and the backboard can be easily removed by angling the two wooden pieces. I plan to gradually lower the price. Size: 30.5 x 27.3 cm No box included. Woodwork Woodcraft
