This item was purchased by my mother, who used to study the tea ceremony, but it was never used and has been stored away. Since I will no longer be using it, I hope someone else can. Although unused, there may be some deterioration due to age. Also, there is a chip on one of the floor tiles. Please see the photos. I am not familiar with this, but the box says "Keiten Saku" (Made by Keiten). There is also the inscription "Keiten" on the kama (tea kettle). I believe this may be Takahashi Keiten, a Living National Treasure.
