I found these at the corner of my kitchen cabinet while de-cluttering it. The left is the small dish which my friend gave me long time ago. Obviously a professional person drew the cherry flower. The smaller shell is a traditional game which is called “kai(shell) awase(putting them together)”. People used to draw a picture on both sides. They put several shells which has different drawing on a tatami mat the outside shell up. You have to find the right match. I had a chance to take a class to draw cherry flower inside of gold paint coated shells. That was so much fun.
