This is a mug by Yumiko Iihoshi. I bought it 10 years ago at her directly managed store in Osaka. I had a few, but I broke some, and it seems I had these remaining ones stored away unused for several years. I'm offering them to someone who needs them! It doesn't seem to have any chips, but it has been used, so there is a feeling of use. Please understand that it has been in someone else's hands before purchasing. I was also listing a small plate, but I've removed it because I found someone to give it to. Height: Approximately 6cm, Diameter: Approximately 10cm
