Dust bag

Ok. So I bought a Christian Louboutin bag on Blue Fly (yeah I'm a dummy). I saw the TV ads and saw they had deals. I believe (no, I know) my purse is a counterfeit. I tried to return it but the whole process sucked. I gave up. I have no need for the duster that it came with. (Its not like I'm trying to keep my fake bag pristine...sacasm). I have no idea what material it's made from. One side is starting to become undone. That's an easy fix.
