Aside from the typical contents I have one or two items which come in handy...
A couple of large bandaids... which have been used for more than stopping blood flow... such as hanging a sign on a door to let some know where we went, or holding a screw on the end of screw driver to allow insertion of said screw into a deep cavity with out loss. I carry the heavy fabric type bands which are incredibly strong (pound for pound stronger than steel... maybe not <img src="images/graemlins/grin.gif" alt="" />)
A credit card sized signal mirror, which has been used for the obvious as well as the clever... such as a make shift flash light (reflecting sun light to check for blown fuses under the dash of a car)
My favorite addition is an old credit card which has been rapped in 20 ft of 60 lb test dacron fishing line, which I then rapped with a foot of folded aluminum foil, then rapped with a couple feet of duct tape and high quality electrical tape (side by side)
This is a handy tape dispenser, I can even pull the fishing line off of one end without unrapping the whole thing... the only thing I can't get at easily is the foil... but its there if needed.
The whole thing is about the thickness of three credit cards, but the utility is easily worth the space. It does fit into a single card slot.
I love when someone wishes out loud for tape, and out of no where I hand them a piece... I always get the "where'd you get that"
