These are buttons for duffle coats. They are a marble pattern combining brown and beige. I think they are perfect for knitwear. Size: Approximately 13mm x 40mm Total: 5 pieces The material is unknown, but I believe they are made of plastic. They are unused and have no noticeable scratches, but they have been stored at home. Please refrain from purchasing if you are concerned. I hope someone will like them. Thank you.
