Dark grey leather. Handles have slides so they can easily be adjusted.
One handle can be hooked to the two top corner rings to convert to a shoulder or cross body bag.
Top is zippered as well as the pocket.
The pocket is on the "body" side for extra security. It measures 5" x 9" which is large enough for any phone. The inside is our standard pocketed lining with 5 pockets, 2 pencil holders & a key holder.
