All of our products are handmade in the U.S.A. using 1/8" parachute cord (paracord). Compared to other nylon cording parachute cord has proven the test of time. Parachute cording does not easily pick or show blemishes. The cord is quick drying, mildew and rot resistant, easy to clean, durable, light weight and ideal for use in making our monkey knot products. We offer the option of various size steel balls, wood balls or standard dice for the monkey fist ball center.
