This appears to be from about 50 years ago. I think it was used as a condiment dish for things like somen noodles, and it's been stored in the cupboard for a long time. Diameter: 8.5cm Depth: 3.5cm It's a small bowl, so I think it would be useful for condiments, appetizers, pickles, or small desserts. I don't have many opportunities to make elaborate dishes, so if you enjoy cooking, please feel free to use it! There were originally 5, but I found one with a chip. If you need the chipped bowl as well, I will include it. Please understand that these are used items before purchasing.
