I bought a black leather Soho large hobo on eBay a couple months ago. (Im pretty illiterate when it comes to Coach, so bare w/me) The leather piece (pully) that is attached to the zipper pull (what is it called, I don't even know what the purpose of it is? lol) is ripped in half. It came to me that way. How do i fix it? Any suggestions?? Thank you!
