This is an obi-ita (obi board) that I received as a gift (*^^*) The person who gave it to me also hadn't used it, and I haven't used it either. However, it has a slight curve because it was bent a little during storage. Since it's unused, it's in beautiful condition with no yellowing or stains. It has a cute chrysanthemum-like pattern (*^^*) Although it's unused, please refrain from purchasing if you are sensitive to minor imperfections due to my personal storage (*^^*) Please feel free to comment if you have any questions (*^*)
