This professional police zip-tie handcuff set is safe, easy to use and lightweight but extremely effective. Suppress any resistance from your sub by inserting the ends through the centre tabs. Once secured, you must cut them off to remove them. They can wrestle as violently as they like, there is no breaking out once they are secured. The strong, flexible plastic allows you to get cuffs nice and tight, in case you have someone who likes to squirm. Can be used around the wrists or ankles.
