The porcelain artist Seigo Yoshimura of Saga province developed a unique technique - after creating the tool on the wheel and drying it half, he carves the glass with a knife. This technique provides a charming and interesting texture for the cup, both for a pleasant grip and for the special look. In addition, Yoshimura gives a personal sun touch by "hugging" the instrument with both hands. This creates a unique form that differs from glass to glass. In the glass you can drink for cold juice, coffee or hot soup.
