The Pack Shack builds durable quality into line packs and briefcases too. Two sizes are available, Regular and Large. Both models include inside organizer pockets for pens, pencils, notebooks and calculators. They also include carrying handles and shoulder straps. The Regular measures 15" X 12" X 3" and includes a main compartment with wrap around zipper and two exterior pockets with Velcro closures. The Large measures 17.5" X 12" X 6". The main zippered compartment is flanked by two, slightly smaller, zipped side pockets. There are also two zippered flat pockets, one on each side, making this briefcase a glutton for paperwork. Made in the USA.
