Seamless. Top quality. Use these crimp tubes with Softflex, Beadalon, or Tigertail. Takes up to 2 strands heavy Softflex - more of the lighter weight beading wires. This is the Tierracast Black - a sort of Metal Noir - black like iron, but shiny.
Crimp tubes are how to finish the end of a beading wire and attach a clasp. Slide the crimp tube on after the last bead, add a jumpring or the loop of the clasp directly, then go back through the crimp tube with the beading wire. Crush the tube flat with your pliers, or better, use crimp pliers to crimp and fold the crimp into a nice, secure completed crimp.
