Square Coffee Cup Set with Brown Glaze - Set includes: 5 coffee cups and 5 saucers - Design: Square-shaped cups - Color: Brown glazed finish - Manufacturer's mark: Stamped on the bottom I believe this is a work of Tousui Kiln in Seto, Aichi Prefecture. I received it as a gift from an elderly relative for a celebration. The color is lovely, and I've only displayed it, so it hasn't been used. Each piece has a unique pattern, adding to its charm. I hope someone who appreciates it will use it. Thank you for looking.
