These professional quality cases are hand crafted in the same way and with the same leather handle and gusset as the Original Leather Series. However, in this portfolio, the body of the side panels is a black woven nylon. This unique combination of material makes the Professional Series a beautiful case that is exceptionally durable and affordable. Each case has two inside pockets and a full twill lining. They come with 8 clear-view presentation sleeves to fit the multi-ring binder. Additional sleeves may be purchased separately too.
