carbone on the left and mezzanotte on the right. Pics borrowed from tokidoki.it where both are now available. Quite similar colours to be realeased at the same time - the straps are also different here.
Carbone is dark gray Mezzanotte is Black. In my opinion the gold trimmings on Black looks a tad more classy, in fact it's very attractive, I've seen it in person.
I didn't think I could ever buy a solid toki either but when I saw the mezzanotte at Macy's I fell in love! The gold accents and the reddish/coral finishing on the sides of the leather....
