I'm wondering if I need to be paying attention to the handles changing color and getting darker? I have a LV Speedy that I bought new from the boutique in San Francisco, and over a 2 year period the handles ended up turning slightly darker than the rest of the vachetta leather. I wipe them down occasionally and do get dirt off them but I'm wondering if the Florentine handles will do that too? And if so, is there anything to be done to prevent it or slow it down? Any feedback is appreciated!!!
