These are high-quality buttons used by designer brands and factory brands. They have a beautiful brown to beige marble color. Approximately 15mm, 20 pieces. There are individual differences due to the natural material. I believe the material is buffalo horn, but please note that there is a possibility of other materials such as nut buttons. Not only for replacing buttons on branded items, but also on Uniqlo and fast fashion items, replacing the buttons will give them a more luxurious feel. I hope someone will use them.
