These are called paracord survival bracelets. They are made with parachute cord that has 550 lb test. They are designed to unravel if you need rope for something. I guess if your Bear Grylles or want to hang yourself because we stink. anyway check them out. The lady is in Tennessee and she makes a nice product. Shipping is free and it came to me in Iowa in 3 days.

Enjoy and Go Dolphins.
Wanting Luck but setting my sights on Barkley, Jones or RG3
