I found this while cleaning out my parents' house. I don't know what kind of pottery it is, but the vibrant colors are beautiful, and I couldn't bring myself to throw it away. I think it's quite old. The inside has vivid red, green, and black colors. The outside has a rough texture. There are no chips or damage. The photos don't quite capture the actual colors. Perhaps image line 14 is close, but I think it's a bit more intense and vibrant in person. The size is: maximum diameter 13.2 cm, height 7 cm. An AI on the internet suggested it might be Karatsu or Chosun Karatsu ware, or Shigaraki ware. Just for your reference. If you like it, please consider purchasing it. There is no original box. I will protect it with cushioning material for shipping. I would like to leave the choice of carrier (Yamato or the post office) up to me.
