One in and a bunch out, to make way for a much anticipated Matte Croc Birkin grail bag that's arrived and stolen my heart. Here's the question: how well does Matte Croc hold up with frequent use? I'd like to cull the herd and keep only a few bags, but need to know if I can count on the Matte Croc Birkin as a daily bag that would be in rotation with just a couple of other bags. When the edges of my non-exotic Birkins get scuffed and/or lose color, a spa treatment takes care of it. What happens when the edges of a Matte Croc Birkin get scuffed or lose color? Can a spa treatment restore it, too?
