Tokunaga Yushin Kiln Yushin Tokunaga, Color-Painted Flower Connection Mug Diameter: Approximately 8.5 cm Height: Approximately 9 cm There is a small chip on the lip. It's slightly rough, but not sharp. There is no problem with the feel on the mouth when used. This is just my personal opinion, so please refrain from purchasing if you are concerned. Please also check the condition in the photos. It can be used as a chopstick holder or pen holder, not just as a mug. It can be shipped together with other items. Because it is handmade, the size, shape, color, pattern, cracks, and glaze application are all different. Black spots, pinholes, distortions, cracks, and small chips on the bottom may be seen, but these are part of the manufacturing process, so please understand the characteristics of the artist.
