Have any of you ever used any white MC stuff with damier pieces like the speedies? My lining doesn't seem to bleed; I've rubbed it hard with a white towel and nothing noticeable came off. However, now that I'm thinking of getting a MC koala wallet to go with it i'm wondering if that's a bad idea, and eventually the lining will turn at least the corners of the MC koala pink....have any of you done this combo and experienced this...?
