These are high-quality buttons used by designer brands and factory brands. They have a beautiful color with light blue to green marbling. Approximately 25mm, 9 pieces Approximately 20mm, 9 pieces Approximately 15mm, 9 pieces There are individual differences due to the natural materials. I believe the material is nut button, but please note that there is a possibility of other materials. Not only for replacing buttons on brand-name items, but also for adding a touch of luxury to Uniqlo and fast fashion items by changing the buttons. I hope someone will use them.
