Un-cold handcuffs / handcuffs

Un-cold handcuffs

This is a paire of modular handcuffs, which is rugged carbon steel wrapped with a ruber outside.It changes the ice-cold feeling and won't hurt criminals and suspects' feelings.Its appearance is not like the traditional ones considering criminals and suspects' feelings.
The handcuffs could be seperated into two parts: a bracelet and a chain. There is GPS inserted in the bracelet so that the police could treat the prisoners in a more gentle way. When prisoners need to wear the handcuffs again, simply connect the two parts.
