Never lose another hat or vest pin again! Replace those old clutch style backs with our Pin Keepers. Slip them on the back, tighten set screw with the included allen wrench and it is done. We suggest cutting of the tip of the pin off with cutters or filing it down blunt after the Pin Keeper is installed. For an extra measure of safety you can even put a drop of Loctite on the set screw! Package includes 12 Pin Keepers and the wrench to install them.
