This is a beautiful blue kiriko glass. I think it would be good as a small bowl or a summer teacup. It seems there are various types like Edo Kiriko, Satsuma Kiriko, and colored overlay kiriko, but I don't know much about them, so please judge from the photos. There is no box or certificate. Used infrequently and in good condition. For someone who will use it. *Not sold separately. *No price reduction on this item alone.
