About this model

My wife has an extensive collection of pins that she likes to display on her purse strap, but was always concerned about losing the backs. We purchased some locking pin backs from amazon, but found that they snag on everything and would bend the pins. We were worried that the repeated bending would cause the pins to break and ultimately cause them to be lost anyway. These guards resolved the snagging issues and the wide base also prevents the pins from bending, thereby relieving both problems with the added benefit of snuggly holding the pin in the desired orientation. Pin backs I ordered are linked below, but should fit any 5mm diameter, 6mm height locking pin back. Can probably scale the Z axis for taller backs if needed, but haven't tested. Why, yes, that is a Red Cross Blood Donor pin.…
