This is a hank of thick cored cotton rope, about 10 mm (3/8 inch) in diameter, with greater visibility for a large audience. Use it for any and all rope effects - Cut and Restored ropes, Knotting Effects, Penetrations, etc. It has a solid hefty feel, and the increased diameter makes it easy to gimmick with rope gimmicks or magnets. Supplied in hanks of 25' white. No instructions included.
