The coil comes with an info card explaining how to use it.

Customer Reviews


5 star rating  Muscle Wires
Thad Johnson from Michigan
I have purchased 3 of these and they are great. It is hard for people to grasp the life like movement of a steel spring. Especially one that "fixes" itself after being ruined by pulling too hard as we all have done to normal springs. Kids and adults love it.
