The Expand-It and Expand-It ULTRA both feature 10 clear vinyl pockets that are 4-inches high by 9 inches wide by 3 inches deep.

Each pocket secures with 2 heavy-duty zippers to seal out dirt, dust and debris and to contain any content spillage within the pocket.

Because the expandable pockets conform to the size and shape of their contents, there is no wasted space to carry to or from home base or your work site as is typical of trunks and other storage systems constructed of rigid materials. Because everything is visual at a glance, there is never a need to un-pack the Expand-It or Expand-It ULTRA to take inventory - inventory as you go!

The exterior of Expand-It and Expand-It ULTRA feature pockets that can be used for color coding a particular bag within a system, or for identifying the inventory inside.  2 additional pockets are Perfect World Luggage's proprietary "Hidden Double" pockets.  These have an exterior side for displaying information and an interior side for keeping private papers private but always handy.  And, of course, we wouldn't forget additional exterior pockets for your business card.
