This item was purchased quite a while ago. As there is no accompanying box, the exact origin is unknown, but based on the atmosphere and texture, it is likely Karatsu ware. However, I cannot make a definitive claim, so please check the photos and only purchase if you are satisfied. Also, there is a mark like a signature stamp on the back of the lid, but I was unable to identify the artist. ※This is a long-term home storage item by an amateur. There may be fine scratches, stains, discoloration, dirt, and dust due to aging. Please check the photos for the condition and only purchase if you understand antique and used items. Please feel free to ask if you have any questions. I am also listing this item on other sites, so please let me know before purchasing.
