These little double cap rivets are super handy for all sorts of fabric and leather projects. You get 100 complete sets (that's the cap, the post, and the second cap). They're made from brass, measure 9mm across the cap with a 7.5mm long stem, and have that classic tubular rivet design where you smash the post to flare it out inside the second cap - it creates a really strong, clean-looking joint. Perfect for repairing things like belts, bags, shoes, caps, or denim where a regular stitch might not be strong enough. They're also great for DIY leathercraft, adding decorative studs to jackets, making pet collars, or even scrapbooking. Because the cap is on both sides, the finished look is neat and professional. You'll need a rivet setting tool (like a hand punch or press) to install them properly. They're small, durable, and a pack of 100 gives you plenty for multiple projects. A basic essential for any repair kit or craft supplies.
