I've seen A LOT of Balenciaga bags with the Silver/Metal tags on the inside and then i've seen some with leather Balenciaga tags, I'm kinda confused because I thought they were all supposed to be metal and not leather?
It depends on the style, take a look in the reference library. Now a days, the RH First and the RH City have the silver plate. That's it. But before, Works used to have them too.
