Should I be paranoid bout the light vernis bags. I know they get color tranfers easy and stained easy but do I have to be super careful or can I be careless with it. And would you use a darker vernis wallet or leather wallet in the lighter bag....I dont want color transfer on the inside either...lol I hope this doesnt sound like a stupid question. I guess I am a little nervous because I only have the damier bag. I have never had a vernis baguntil now.
