These are high-quality buttons used in prêt-à-porter and factory brands. They have a beautiful color, with a beige outer ring and a brown marble pattern inside. Approximately 20.5mm, 5 pieces Approximately 15.5mm, 1 piece Please note that there may be individual differences due to the natural materials. Not only can they be used to replace buttons on brand-name items, but they can also add a touch of luxury to items from Uniqlo and fast fashion brands. I hope someone will use them.
