This is a Showa-era children's rice bowl. It's unused, as I purchased it from an old stock of a tableware wholesaler. Diameter: 9.5cm As it's a miscellaneous item, there may be color fading, cracks, chips, and stains. Please purchase if you understand that it's an old item. Please refrain from purchasing if you are overly concerned about details. It will be shipped via Yu-Packet Post Plus.
