Thank you for visiting. Thank you in advance. This is a guinomi (sake cup) from a famous indigo-colored ceramic artist, though I don't know their name. I received it over 20 years ago from a wealthy acquaintance. I'm not very interested in new things, and I don't drink alcohol, so I haven't used it myself. I'm putting it up for sale because I'd like someone who is interested in ceramics to use it. It's heavy (300g) and fits comfortably in the hand. I don't know the meaning of the white spot in the third photo; could someone please tell me? Size: ・Height: 5cm ・Outer diameter: 8cm x Inner diameter: 5.5cm ・Height: 7cm, Depth: 6.5cm ・Foot: 5cm diameter Since it's old, please purchase it with the understanding that no returns or exchanges are accepted. Please confirm everything before making a purchase. Thank you very much.
