I accidentally purchased the wrong size, so I will ship it as is. The following is the product description: Color: Gold Brand: Sozomi Co., Ltd. Manufacturer: Sozomi Co., Ltd. Quantity: 100 sets (100 heads and 100 legs each, within 5 errors) / Color: Gold Size: Long leg type, head diameter 9mm, leg 9mm, leg length 10.5mm / Material: Iron [Simply tap to install] This is an easy-to-use leathercraft rivet set. When installing, please attach the rivet so that the leg protrudes slightly. [Dedicated tools (sold separately)] For installation, you will need a rivet setting tool that matches the diameter of the head. Also, a hole punch, a setting base, and a hammer will be helpful for installation. We also handle rivet setting tools and setting bases that are compatible with these rivets. [Compatible with various materials] Can be used for leather accessories, leather keychains, PVC clear pouches, leather/fabric bags, synthetic leather strap fasteners, leather apparel, jeans, and a wide range of other materials. * Please select the long leg (leg length 8-10mm) rivets according to the thickness of the fabric. If the fabric is about 5mm thick, we recommend using standard leg (leg length 6-7mm) rivets.
