Chado (Japanese Tea Ceremony) Hanaire Shikita (Thin Board) Sugi Kakuhamagita (Cedar Square Clam-Shaped Board) Clam-Shaped Edge Thin Board The side that was used has faint water stains from the bottom of the hanaire (flower vase). I believe both sides can be used. As shown in the photo, the other side has no noticeable stains, so those who are concerned can use this side. The side with the water stains does not have large rings, so they will be hidden when the hanaire is placed on it. (Diameter: 7cm) Other than the round stains, there are no noticeable scratches or stains. Paper box (slightly aged and stained) Size: Length: 41cm Width: 29cm Thickness: 7mm
