Calling all leatherworkers and DIY enthusiasts! This 25-set collection of copper rivets and burrs is perfect for all your crafting and repair projects. Each rivet measures 12mm in diameter with a 4mm pin and 19mm height, paired with matching washers that create super secure fastenings. Made from solid copper, these rivets are corrosion-resistant, durable, and have that classic warm tone that looks amazing on leather goods. They're perfect for making or repairing belts, bags, purses, keychains, shoes, jeans - you name it. Installation is satisfyingly simple: punch a hole in your material, insert the rivet, place the washer on the back, hammer it down, trim any excess pin with pliers, and flatten the end. The result is a professional-looking connection that's way stronger than stitching alone. No tools are included, so make sure you've got a hammer, hole punch, and pliers handy. Whether you're a seasoned leather crafter or just getting started with DIY repairs, having a supply of quality rivets on hand is essential. Twenty-five complete sets give you plenty to work with for multiple projects. Get creative and make something that lasts!
