You must have bought the self adhesive
Ace bandage. I like to use this one as an outside layer for my wrap for when i hang to keep everything together nice and snug. Just go back to the store you bought it from (I buy mine from walmart) and ask if they just have a normal tensor bandage because you hurt your arm and you need one. Also, if you don't want the self adhesive one you can try to see if they will let you return it for a refund.
