This is a short video on how to put on a cuff without damaging it.
Cuffs can be damaged by repeated pulling open and squeezing shut actions. This will weaken the metal until it cracks, which can be impossible to repair as it has damaged the structure of the metal. Never reshape your cuff in this way. Instead, aim to put the cuff on higher up than your wrist, on the fleshy part of your arm, then slide it down into place, then simply reverse this to take it off again.
