Crimp tubes offer a secure and professional finish for all types of jewelry designs. Use crimp tubes to create illusion designs showcasing the wire. Incorporate the crimp tube into your design as an accent or spacer bead. They are consistently sized and made from tempered brass to withstand crimping and rounding without cracking. The parts are tumbled to remove burrs and then plated using a special process to maintain ductility. The piece counts provided are averages and approximates, not exact counts. Packaged and sold by weight.
