We offer together with disposable handcuffs HT-01-Y or HT-01-B also their training version HT-01-T in red colour, which makes it possible to train handcuffing techniques without necessity of destroying real disposable handcuffs. These handcuffs are equipped instead of fixation locks with silicon friction rollers, which enable smooth and easy fixation of handcuffs. They, however, exert slight resistance when the handcuffed person tries to release himself or herself from the handcuffs. They thus imitate behaviour of real handcuffs, but can be easily and safely taken off.
