REUSEABLE (you can poke a flat screwdriver into the connectors to undo the cuffs)
Plastic handcuffs (also called PlastiCuffs or FlexiCuffs) are a form of physical restraint for the hands, using plastic straps. They function as handcuffs but are cheaper and easier to carry than metal handcuffs, and cannot be reused.
Traditional form of plastic handcuffs are cable ties,
either two interlocking straps, or a single cable tie around both
wrists. More recently, plastics-manufacturing companies have started to
produce special devices comprising two interconnected straps as one
item. These are generally injection moulded nylon items, selling for tens of cents each. The low cost and light weight of plastic handcuffs has made them popular with police and military forces when they anticipate a large number of arrests, as in riot control or demonstrations. An advantage of disposable restraints is avoidance of transmission of communicable disease; metal handcuffs can spread disease through reuse (from blood or other bodily fluids that may not have been cleaned off the cuffs), disposable restraints are not used on multiple subjects.
