This belonged to my grandmother and was at her home. It was stored in a wooden box. She used to practice the tea ceremony, so I think she received these as gifts when she retired or on other occasions. The names of the people involved are written on the back of the top of the wooden box. I believe it's a set consisting of a teapot and something to warm it. I don't know anything about it, so I apologize. Although it's unused, it has been stored in a storage room for a long time, so please understand this before purchasing.
