Hello Beautiful Beader,
These wonderful crimping pliers will change the way that you bead! They take a tubular shaped crimp tube and make it into a bead while cinching it down onto the nylon coating of the wire. I highly suggest that you stick to using Soft Flex crimps and beading wire for the best connection. Our crimps have double the wall thickness of most and therefore work very well with these pliers. Our beading wire has a premium nylon coating that allows the crimp to cinch down tightly. Some of the other brands use a nylon that is too slick to get a really good and strong connection.
