Truly nothing is as soft or as smooth as silk jewelry cord! Silk cord, also referred to as Naturseide, is the traditional stringing material used by beaders for centuries. Each 100% silk bead cord has a twisted stainless steel needle at the end, saving you precious threading time! Doubling the thread is unnecessary, and the cord can be easily knotted because the thread has the correct twist. Each card contains approximately 79 inches of cord.
