Spare Nozzles x 10

Each resin cartridge purchased, is supplied with a nozzle.  What we have here are 10 x Spare Nozzles. If part-using epoxy resin, you must use a fresh nozzle as the previous one, with use, would have clogged up and hardened, thus making it unusable. It is not recommend to part-use Polyurethane Resin.
