Pottery? Hina dolls Compact and easy to display. - Design: Hina dolls - Material: Pottery? - Colors: White, gold, red, black - Features: Comes with a seashell-shaped case - Size: Small, for display Thank you for viewing. Mercari AI suggested "pottery." The appearance is pottery-like, but it's light. I don't think it's pottery. It feels like light clay or Bakelite in terms of stability. They are sized to fit on a large clam shell.
