Exposed corner pins trash file covers and scratch whatever's underneath them. This adhesive patch solves that — stick it inside your file cover, thread the metal pin through the pre-punched hole, and the patch covers the sharp pin end so it can't damage anything. Strong PVC construction withstands constant pulling and wear. Comes in a dispenser roll of 200, fits all Celco metal pin sizes. Essential for NZ offices and schools protecting their files.
