Probably Kasama-yaki (Kasama ware). This is a brand new, unused pair of rice bowls for a married couple. They are not for sale separately. Please refrain from purchasing if you are overly concerned about minor details. Left bowl size: Approximately 5.5cm high, 11.5cm in diameter. Right bowl size: Approximately 5.7cm high, 13cm in diameter. I also have other pottery items for sale, mainly Mashiko-yaki and Kasama-yaki. Please take a look if you'd like. Artist: Artisan made.
