There's a difference between lifting straps and wrist wraps. Wrist wraps supports your wrists while doing heavy pushing movements as for lifting straps it supports your grip while doing pulling movements.

Musclemania have one.

you sprained your wrist during what exercise ? might want to fix the form or the way you grip the bar?

also straps and wrap is different thing, you hardly need wrist wrap unless you are pressing a huge amount of weight, or low bar squatting heavy
