Louis Vuitton's Ardoisé Taiga Agenda is the medium-size agenda, which is a good size for the desk, briefcase, or bag! A unisex agenda, Taiga is sturdy and wearable textured leather and this agenda has a narrow flap with a snap that opens to a six ring binder, a large slide pocket, a medium slide pocket, six credit card slots, as well as a pen holder. There is a little wear on the hardware, inside, and on the front, although it's hard to see. Ardoisé means slate-gray, just as you were hoping!
