Arita-yaki (Arita porcelain) in red letters on the box. Signed with the artist's name: Kizan. A set of 5 medium-sized bowls and a wooden box. The character "kisen" is written on the back. The bowls have a rustic, rough texture like that of Rosanjin, and are decorated with cherry blossom paintings. I opened the box for photography, but they were stored wrapped in packaging material, one dish at a time. Although they are unused, they have been stored for about 20 years, so the wooden box shows some signs of deterioration. Please consider purchasing if you understand that these have been stored at home.
