I don't think black is great for turning age into those great patterns some leather products get. For my money the darker browns like chestnut or mahogany are the best at turning life's nicks and bumps into a good looking piece of leather. My SLC phone sleeve is black but I don't expect it to be my phone sleeve for decades, I just like the clean look of black with my phone and that particular object. I think the black will look pretty much like it does now, maybe a bit of gray in some patches, several years down the line. I've got a mahogany Custom Hide briefcase that has aged into some great looking leather, and a black satchel from a small craftsman in my town that looks pretty much the same, though it has a bit of a road weary look about it that I think is nice. Bottom line, the black will look good but i wouldn't expect too much character soon.
