Multicolor Kutani-yaki brooch, made of ceramic with a safety pin closure. - Colors: Multicolor (red, blue, green, yellow) - Material: Ceramic - Back pin: Safety pin - Engraving: Kutani Thank you for viewing. It's an oval brooch, 4cm x 3cm. I think I bought it as a souvenir a long time ago. I never had a chance to use it, and I unearthed it from the back of a drawer. It has been stored at home for a long time. I will wrap it in bubble wrap and ship it via regular mail, Click Post, or Mercari delivery, whichever is the cheapest method.
