Can't believe it, but my ruby wed wine Vaja T66 case is already starting to show signs of age. near the top flap (where the magnets are), some unremovable black muck or black scratches are starting to appear (much like a small virus!) There is some removable black sumdge elsewhere on the case, but that's an easy fix of course. Does Vaja--or some other organization--sell polish in different colors?
