Mishima Kazuchawan, made by Yoneyama, with a wooden box. These are 10 powdered slip tea bowls. Approximately 11.7 x 6.3 cm, with slight variations between individual pieces. I brought these from my grandmother's house, so I don't know the details, but I believe they are good quality. I am clearing out the storage room, so please take a look at my other items as well. No claims and no returns. Thank you for looking.
