These are high-quality buttons that were intended for use in designer brands and factory brands. They have a beautiful, slightly greenish light gray color. Approximately 20mm - 24 pieces Approximately 15mm - 24 pieces There are individual differences due to the natural materials. I believe the material is buffalo horn, but please note that there is also the possibility of other materials such as nut buttons. Not only for replacing buttons on brand-name items, but also for adding a touch of luxury to items from Uniqlo and fast fashion brands. I hope someone will use them.
