I bought these at a general goods store for 1500 yen each! They are celadon-colored pottery with a design that has protrusions on the bottom for stability. I'm thinking of selling them as a set of 6. For those who love Japanese tableware and dishes, please consider them! - Shape: Shallow bowl - Color: Gray-ish - Material: Pottery - Size: Approximately 15cm diameter x 13cm - Features: Protrusions on the bottom Thank you for looking.
