Very nice but...
Color: B-brown
It's a beautiful bag but the outside zipper pockets are deceiving, they're very small . My phone couldn't fit inside. No bad smell, the organization inside is good and the strap length is pefect. Because the outside zipper pockets are too small I may have to return it.

Good quantity
Color: A-shiny Brown
Perfect size for me. The different compartments makes it easier for organizing. Has a mild order but after turning it inside out and put it in the sun for a few minutes, problem solved.
