Not too slim to be a portfolio and not too thick to be a full-size briefcase. Here is a slim leather briefcase that hits the perfect spot in thinness.
The Thomson 2211 is 16″ x 12″ with only a 2″ thin gusset. Fine hand-stitched English bridle leather with burnished edges and a brass tube key lock. Slips comfortably under the arm or gripped in the hand.
