This is Tsuboya ware from around the 19th to 20th centuries. As the image shows, the rim has been repaired, and there are several areas where the glaze has chipped off. After cleaning, I have used it several times to prepare matcha. There are also cracks (nyu), but it doesn't leak. The glaze texture of this type is rare. Diameter: Approximately 10.5cm Height: Approximately 8.7cm Sizes are approximate. As it is an old item, there are scratches and stains commensurate with its age. The color may differ slightly between the actual item and the image. There is a kiln scar on the waist. Please examine the description and images carefully before purchasing.
