This item is from my home storage. The box it came in was labeled "China Ware Tea Set." The material felt like old plastic, so I broke one of the multiple pieces. It turned out to be a material similar to cardboard, like hardened clay. It weighs approximately 123g and is light. The surface is hard, but it breaks relatively easily with force. It also becomes soft when soaked in water. I will ship it via Yu-Packet Post without the original box.
