These are high-quality buttons used by designer brands and factory brands. They have a beautiful light brown to beige marble color. Approximately 15.5mm, 30 pieces. There are individual differences due to the natural material. I believe the material is buffalo horn button, but there is also the possibility of other materials such as nut buttons, so please be aware of this. Not only for replacing buttons on brand-name 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.
