They provide a clean, professional look and are easily adjustable or removable, which is good for leather goods like bags, belts, watch straps, and wallets. Made from metal, these leather rivets are resistant to corrosion and wear, ensuring long-lasting performance. Their sleek design blends seamlessly into leather products, enhancing overall appearance. Widely applicable in attaching straps, reinforcing stress points, or binding book covers or used in belts, and handbags for both functional and decorative purposes. Unlike traditional rivets, they don't require special setting tools and can be installed or removed with a simple screwdriver. Ensure the holes are properly sized to avoid splitting the material or making it too loose.
