Our cord is Poly sheath and Poly core, and absorbs quite a bit less water than nylon cords. It is also quite a bit more static, so you won't need to fight the stretch. Works better! After using a very pretty but very stretchy nylon accessory cord as pull cord for a couple of years, I figured it was time to make some 100% Polyester pull cord for superior performance.
NOTE: We do sell this item at .55 cents per foot separately. Please call/message for availability.
