It was quite a while ago, but I bought a set of 5, and I've used 2 of them. I don't know the artist's name, but according to the shop staff, they are from Kyushu and are known for their unique soil and firing methods. As you can see in the photos, they have a rough texture. I bought the set of 5 for 35,000 yen at the time. They have been stored at home but are in good condition. The photos may have slight differences, but the colors are close to the actual items.
