This Stone Oil Leather Satchel is 13 inches wide, 11.5 inches tall, and 4 inches deep. It has a pocket on the inside for a tablet, as well as pockets, pen holders, and space for binders, books, and folders. The re-sizable strap attaches using solid brass trigger snaps. This is my second bag, and it was made as sort of a commission. The next bag will be courier style and large enough to hold my DSLR.
