1/2" Miniature Metal Bolt Snaps are nickel plated, die cast zinc. *Currently these bolt snaps come to us with different "strap eye" shapes, such as round, and square.  When you order a large volume you may get a mix as well, so if you would like them to be all the same, please request this in the order comments.  Made for light duty products. The 1/2" Miniature snaps measures almost 1 1/2" in length, so don't let the "1/2" fool you! These are mostly made for a decorative piece, not to hold any certain amount of weight. For example, you can use them on a mini purse zipper accent, just don't expect to use it on a 1/2" leash and plan on your dog staying around! We currently offer 19 metal hardware colors that for a small additional cost, you can get these colored!
