From Kawamura Glass Crafts Co., Ltd. Unused, but has been stored at home for a very long time. It was a gift and has been stored in its original outer box. The back of the box in the first photo is dirty, so it will be packed in a different box for shipping. The instruction manual in photos 5 and 6 also shows signs of aging and soiling, but will be included. The plates are 11.5cm wide and 8.5cm long. They are slightly smaller than side plates. The surface is smooth, and the underside has a rough texture. Shipping will be via Rakuraku Mercari Delivery, but may be changed to Yu-Yu Mercari Delivery. As it was a gift, I do not have detailed information about the product. I will not sell them individually, so please understand.
