How should you put the brace on and adjust it so that it holds but does not constrict the hand? — Wrist rest 500

The card gives no detailed instructions on putting the brace on: it says that the brace is put on directly on the body, secured with a fastener and fits tightly around the joint area; it suits both wrists. Warnings on the card: for external use only; do not use if you are hypersensitive to the components; if allergic reactions occur, stop use and see a doctor; avoid contact with the eyes and mucous membranes; keep out of the reach of children.

General information (not a manufacturer's instruction): the brace should support the wrist but not constrict the hand — if the fingers go numb, tingle, turn pale or blue, or the pain increases, loosen the fastener or take the brace off; with long-term wear take breaks and watch the skin. Use on a doctor's recommendation.
