Size 32 slate and shell go stones.
Think it is Moon grade, a step up from Jitsuyo. The white stones often have more fine thin stripes and are a bit whiter.
No chips or cracks, a few could do with a little clean up.
Bought new about 5 years ago from Aoyama gobanten in Japan.
Smoke and pet free home.
Keyaki go bowls made in Japan fit up to about size 33.
Also have another item, a table go board for sale separately.
