10 Brass / Gold Pin Lock Backs Guard Saver for Disney, Olympic, Harley, Hard Rock, Rodeo, Police and other metal pin post pins. These pin locks are absolutely the best I have ever used. Protect your pins from getting lost or from falling out of your pin book. No more painfull finger stabing.   My kids will never use the rubber backs anymore (except for pin trading).  You wont be disappointed with these locking backs!

No tools required, No set-screws to loosen up,  Just push on and it's secured. Squeeze-pull on the little flange on the back to release the spring locking.
