I've been carefully storing these, but I have too many teacups, so I'm selling them. Matsuhai and Shino glaze. No box. Microwave safe. Dishwasher and oven NOT safe. Notes: ・Crazing is visible on the surface. ・There are multiple tiny pinholes (stone bursts) both inside and outside. Each piece is handmade. Please refrain from purchasing if you are concerned about minor imperfections.
