I'd like to find a source of small quantities of security pins. I'm thinking of the refill packs for pinning kits but with spools, mushrooms, serrated pins and whatever else is available.
I have a large number of mortise, rim, and kik cylinders and I would like to start experiment with security pins in these. I currently have a few padlocks with security pins but I want something I can re-pin quickly and easily to practice with.
Thanks in advance.
