Comes in a storage bag, among the small touches that inspire an overall feeling of quality. Pleasant odor (not too strong, but this) leather at first.
A large pocket not so big, two zipped side pockets (ok for a few sheets, a checkbook ...), and a pocket between the main pocket and the flap, which allows you to drag a magazine for example. 3 or 4 small storage space in the main pocket. Overall it is well appointed and functional.
Beware though, I think it's a little small for a 15 inch. Anyway mine is too broad. A 13 inches with a protective case should go smoothly.
The bag is beautiful, pretty neutral and can be worn with almost everything. Overall satisfied!
