Coasters made from Okushizu wood from Shizuoka City Brand new, unused. Individually packaged and sealed. I received these at an event related to building materials in Shizuoka, but I didn't use them, so I'm selling them. I've stored them at home for about a year. About Okushizu Wood: It seems to be wood harvested from the mountainous areas of Shizuoka. Approximate size: 9cm (length) x 9cm (width), 6mm (thickness)
