I have the monogram and to date it is fine but i dont just throw my blusher brushes in without putting a cover on them. If you are careful then it should be fine but the azur will be more easily stained x
I rotate mine daily--I have the pomme and black mc which I purchased over the summer. My pomme has slight black marks on the leather tab from tarnish from the zipper pull and I got a little lip gloss on the vachetta heatstamp tab inside. Other than that--the inside and outside are both great and they can easily be wiped with baby wipes.
