Velcro 101
Inside your box of industrial strength Velcro you will find two different feeling 15-foot belts.
One belt will feel soft and fuzzy. So we'll refer to this as the "FUZZ" side .
The other belt will feel rough and is covered in tiny hooks. So we'll refer to this one as the "HOOK" side.
Assuming that you ever owned a pair of sneakers in the late eighties, you probably already know what happens when you put those two different sides together. But this is not the wimpy Velcro that you used to fasten your shoes in middle-school. Industrial strength Velcro has incredible sticking power. As I learned the hard way, it's not a great idea to test these cuffs out on yourself when there is nobody else around. They are surprisingly challenging to get out of!
