This is .8mm braided Chinese nylon that is a great media to string on. It has a little stretch but will re-bound once pulled. It is strong and resists cutting and fraying. The cord will melt under a flame or high-heat source so you can heat-seat the ends once tying.
This cord will tie into very secure knots yet it the knots can be un-tied without damaging the cord if you work at it.
I recommend pre-stretching the cord before stringing.
This cord is sold by the linear foot and is available in several colors. If you order 25′ or more it will be divided into 25′ bundles for easier use.
Contact me if you are looking for something other than these colors.
If you need 1.5mm cord it is also available.
