This is for (1) US Ropes 650 Paracord of 100 feet. This cord has the same outer sheath strength of 550 paracord, but without the inner core. This allows for a flat cord that can be used where a more rounded cord could create abrasion. This cord is great for outdoor use as it is weather resistant and can withstand harsh environments. 650 paracord is a great tool for boating, camping, crafts, and much more.
