When I visited my friend Mari in Japan, we went to one of her favorite antique shops that was not in a tourist section so the prices were more reasonable.
I found an item that I liked and decided to purchase, and then the shop owner said that with the purchase, we could select small items from a certain table for free.
This small celadon porcelain vase was one of the items. The top has a small hole to be used as a bud vase and is designed to come off like a lid - for easy cleaning.
The color is a blue-green that I am crazy about.
