Approximately 20mm Approximately 15mm Reinforcement buttons, 30 pieces each 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 for adding a touch of luxury to Uniqlo and fast fashion items by changing the buttons. I hope someone will use them.
