Made from polyester, rubber, and alloy metal, our barbed cord is sturdy and durable, and will not irritate skin. Available in sizes from 6.5 inches to 20 inches, our cord is 2mm thick and each barb is 0.6mm long. We also have just the barbs without the cord available for larger mm cord, and the metal ends of the barbs are smooth and will not cut or snag. Elastic barbed cord can be used to string face masks or hats, fasten folders or portfolios, or display products or promotional items. Durable and stretchy, this barbed cord stretched to 100% of its original length and the barbs are securely mounted onto the fray-free cord ends.
