These are high-quality buttons used in prêt-à-porter and factory brands. They have a beautiful light brown color with ivory marbling. Approximately 20.5mm, 20 pieces. There are individual differences due to the natural materials. I believe the material is buffalo horn, 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, changing the buttons will give them a more luxurious feel. I hope someone will use them.
