These are high-quality buttons that were intended for use in designer and factory brands. They have a beautiful, slightly grayish color, like olive green to military green. Approximately 20mm, 6 pieces Approximately 15mm, 8 pieces There are individual differences due to the natural materials. 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 brand-name items, but also on Uniqlo and fast fashion items, changing the buttons will give them a more luxurious feel. I hope someone will use them.
