The handle, which is hand-kneaded one by one, is a little thicker than usual so that it can be held tightly. The four colors of Setoguro (glossy black), Shino (natural white), Oribe (deep green), and Kiseto (warm yellow) are the traditional colors of Mino ware, which have been handed down for 1,000 years.
