This is a set of 4 double-sided rivets. I only needed a few, but the ones that fit the size had a larger quantity, so I'm selling the extras. The optimal fabric thickness for these is about 5mm. Size: Round part diameter 7.2cm, leg length 8mm (approximately 5mm when compressed) ※ There are listings A, B, and C for double-sided rivets, but they are all the same (I've assigned letters for my own distinction) ※ This is a set of 4, but I can also make it a set of 6 for the same price. If you want a set of 6, please comment before purchasing. * I have other items for sale too! * * I offer discounts for multiple purchases!
