I'm not sure how these were stored, possibly at home. 5 plates, 9 cm in diameter. I think the design is very cute. I don't know when they were made, but they have a retro and fun atmosphere, so I'm listing them as Showa retro. As you can see in the fourth photo, there are parts on the back of the plates that look wavy. This gives them a vintage glass feel, which I like. The front surface is smooth. The glass emits a gentle, soft light. There are no chips or cracks.
