Lacks flexibility.
Color: Coffee
The leather on this bag is very stiff, with no flexibility. Interior difficult to access due to the stiffness of the leather. The design is simple and attractive with nice finishes on the bag. Unfortunately, the leather is just too inflexible in my opinion.

Beautiful leather bag
Color: Brown
The quality of this did not disappoint and seems top notch. I was pleasantly surprised when I got it. I would have thought it cost hundreds of dollars if it had a certain big brand logo on it. The brown is beautiful.
