Dry Bones Kuniyoshi's Cat Skull Ring. This ring features a very unique design: cats from Kuniyoshi's paintings, arranged in a skull pattern, mirroring the kimono patterns in his art. The inner diameter is about 18.3mm, which is approximately size 16-17. It's quite thick and has a substantial weight. It seems this item is no longer available in shops, making it a rare find. A must-have item for skull and cat lovers.
