Pearl color: White with a hint of pink Pearl size: Approximately 8mm per bead, diameter approximately 4.5cm 3 beads approximately 7mm, length 10.5cm 13 beads approximately 7mm, diameter approximately 5cm This brooch has a slightly nostalgic, Showa-retro feel. Adding it to a simple outfit will instantly make your personality shine. I think it's beautiful. Please check the photos. I am an amateur, so I don't know the details. The box case is not included.
