If you understand the profile, you can buy it immediately. This is a black arm sling type, with a pocket that is convenient for holding things like handkerchiefs. My son used it for about a month while washing it when he broke his arm. It's easier to put on than a triangular bandage because it can be easily attached like a shoulder bag. It can be used on either the left or right arm. #FractureConvenienceGoods #PlasterCast #Splint #TriangularBandage #FractureCare
