I have a black MC Koala wallet, do not like the coin compartment, and would like to get a coin cles for it. Was at boutique today and fell in love with the violet vernis cles, but I am worried that it will scratch easily. And I know that patent leather tend to have color transfer problems. I am worried that the vernis cles will get ruined due to those problems. Does anyone here own any piece of vernis cles/wallet? How long have you owned them, and do you have any problems with them? Thanx in advance for your help, LV ladies and gents.
