I used to worry and worry about losing my pins, and rarely took them out of my apartment, until I discovered these locking metal clasps.  Once you decide on a more "permanent" place for your pin like a backpack or handbag, you can easily attach this clasp and never have to worry about it coming off again!  This is a great upgrade from the rubber backs which wear over time and come off a little more easily.  I have yet to lose a pin with these locking clasps!  You will receive (20) locking clasps.  Add them to a pin order and try them for yourself!
