Hi, all! My first post in the forum but have been lurking for a while

I have a couple of questions.
1. Has anyone seen this happen to an older hangtag? It's like it split apart. Would it be ok to glue it back together or is there something special I should do?
2. I thrifted this older NYC 0318 bag because I loved the style. I was going to give it a bath but I'm a little worried because the leather feels very different than all of the other
Coach bags I've come across. The outside almost feels "waxy" and stiffer. And the reverse side is smoother and not rough like most. Anyone have thoughts about whether this one actually is different or should be treated differently?
Thanks!
