I am a teacher with the back to school blues and I am going to get myself a little LV treat. I am deciding between the ZCP in mono (or DE) or the Cles in Pomme. I currently carry Neverfull with a Mono Zippy wallet, but I never carry my LV purses to school. I want something to toss into my tote bag that can store my license, debit card, school ID, insurance card and some cash. I like that the Cles can attach to my keys but I am worried about damaging the vernis leather. I like that the ZCP is a real wallet, but I already have the full size zippy. Thanks in advance for the help!
