This is an item left by my grandfather, who loved antiques. My grandfather said that this item was "the most valuable of all the antiques I own." I don't know the value of tea bowls, so I am listing this based only on my knowledge of Kuma-kawa tea bowls that I researched online. ① A memo from my grandfather that says "Mid-Joseon period Kuma-kawa tea bowl" ② A sticker on the box that says "Korean celadon tea bowls" However, I have not had it authenticated. It is an old item, so there is some dirt and the original texture of the pottery, but there are no chips or cracks.
