Horn button Horn button Buffalo horn button Genuine buffalo horn button Four-hole 20 millimeters 20mm 4 pieces These are new buttons. How about using them to replace buttons on a coat? Since they are made of natural buffalo horn, each one has a different appearance. I will send the ones in the photo. They are black. There are individual differences due to the natural material. The quantity can be increased or decreased. Please inquire in the comments section. Thank you.
