I changed my Cuff design a bit and came up with these guys, I really like them and they should be able to withstand some abuse. The black strips are actually double-sided Velcro and it is really strong. You are not going to be able to get out of them. I am going to sell these for $25 a pair or $40 for a set of 4 Shipped to the US. Shipping to Canada or Europe will be a few more dollars.

I can get the Velcro in a few different colors and can do the base in almost any.

Note me if interested
