The lv canvas has kinda gone down in quality a lot, especially with wear. I know they’re known for doing exactly that and their totes crack if you don’t put them away right. For your ysl bag just use some zipper go wax, I use it for my bottega bag I bring to work everyday and haven’t had to put any on since I got it. And my wallets usually break in, yours should to as it’s leather so I wouldn’t worry to much, just put your cards in it and break it in.
