This is the real deal rope for magicians, I have used rope professionally in my shows for 30 years , it seems to be the only place that sells 12mm rope that is actually 12mm and not thinner. Good price for postage as well.

This was the only place I could source this size (12mm) hollow pure cotton rope. product seems fine, price reasonable for quantity (albeit more than I needed) item as described, and delivery fast, with tracking (from dpd)
