Mug for All / Miyuki Matsuo Collaboration with Yamaka Shoten A set of 4 oval plates designed by illustrator Miyuki Matsuo. Convenient size for a wide range of uses, such as curry, pasta, and salad. ■Size: Approximately 19.5 x 24 x 4 cm ■Material: Porcelain (Made in Japan) ■Specifications: Microwave safe, dishwasher safe I think I've used the plates about 3 times, except for the light blue flower one. I'm selling them because I have too many dishes and don't have a chance to use them. I think they are clean with no noticeable cutlery marks. Thank you for your understanding.
