Thank you for looking. Here are 5 buttons made of black mother-of-pearl, each approximately 20mm in diameter. Since they are made from natural shells, each has a different pattern and curvature. There are areas on the surface that look like scratches, but these are from the time of purchase. Please refrain from purchasing if you are concerned. My family member stopped sewing, so I am selling these. They are unused, but please consider that they have been stored at home. They will be sent in simple packaging via Yu-packet Post Mini or Nekopos. Thank you.
