“Dots” Sake Set is Koishiwara Pottery clan from Touhou Village in Fukuoka Prefecture. This Sake Set has continuous dots pattern on the surface. Recycled old watch’s mainspring creates this pattern. Old Mainspring is straightened and sharpened. Place product on potter’s wheel, then spin it and apply this mainspring. The mainspring shaves certain parts of clay in the same interval, creating continuous dots pattern on the products. This dots pattern makes sake cup and flask very authentic and cute in our opinion. Dots flask is also good to serve source, and cups are good for condiments containers or servers, too.
