This pack of 4 locking pin backs is designed to keep your pins firmly in place, even when worn on highly used items. Choose silver or gold. To lock the back, press into the post firmly; you can test if it's secure by carefully trying to pull it off the post. To remove, hold the pin and pull up on the spring-loaded trigger at the top of the locking pin backs. Avoid forceful removal and do not put your pin in the washing machine with a locking back attached, as it may break the pin and locking pin backs.
