This comfortable wrapping wire is made of high-strength, corrosion resistant stainless steel with a flexible, protective plastic jacket. The clear, kink resistant coating has a spongy feel that is smooth on your fingers and easy to twist. You can wrap tight, secure knots without puncturing your fingers or wrestling with stiff, sharp ends. Super-SoftStrand is corrosion resistant and will retain its strength and finish longer than uncoated common steel wires.
