From Thinkgeek:

These Star Trek TNG Uniform Messenger Bags feature the red, blue, and gold division colors of ST:TNG along with a metal combadge affixed to the exterior. The interior features a sweet ST:TNG-themed lining and padding all around. Underneath the flap, which secures with magnets and a strap, the top closes with a zipper to keep all your stuff safe. But probably the most unique aspect of this bag is right above the organizer section under the flap – it’s got pips! Each bag comes with 4 gold pips (cleverly rendered as riveted snaps) and 1 black pip so you can tell the world how you rank.
