How long have you had your caviar bags? Are there scratches yet? Do you condition or treat the leather in anyway? I'm *this* close to getting a medallion tote (I'm taking LV Duomo off my wish list). Just want to make sure the caviar really is tough & will take a beating. What about the leather lining on the inside? Is it just normal leather? Will it get scratched by keys, pens, etc? Thanks so much for your help.
