Reading in a forest where butterflies dance. A cute black cat. A romantic obi-dome (sash fastener). The back has two sanbu-gumi (three-strand cord) parts. The diameter is a little over 2.5 cm. The cabochon part is smooth and round, and it's a beautiful item that lets light pass through. #TsumuraObidome I also sell obi-dome at a reasonable price. Please take a look.
