Single cap snap rivets are great for joining leather. Push the stem through a hole in pieces that you want to join together, and then put the cap on top of the stem. Use a rivet setter to maintain the convex shape of rivet cap. Give a finished look on one side of your projects and hollow/flat on bottom side. Particularly good for making and mending handbag straps and similar items. Package Includes: 100 x Single Cap Rivets (stem and cap) 8mm stem length
