This is a set of 20 pairs of snap buttons (^o^) These are not buttons that you sew on with thread, and since there are no holes to sew thread through, you can attach them securely with glue. To attach the snap buttons, it's easier to hammer them in with a punch, but you can also pinch them together with pliers❗️ As shown in photo 2, overlap the two pieces facing upwards and hammer them together (^o^) It takes a little bit of force❗️ Size: Approximately 9 x 7mm Color: Matte Gold Material: Alloy Quantity: 20 pairs I also have other accessory parts for sale, and I offer a combined shipping discount if you purchase multiple items (*^▽^*) Please note that these are imported products and may contain color unevenness or uneven plating. Please consider this before purchasing m(__)m Discounts on single items are not available. Various parts Snap buttons Mask earrings
