The actual bag is a Condor brand model; MA54 T & T POUCH
The bag measures approximately 8"x10" and is MOLLE compatible as well as has two D-rings on the back for attaching it to a strap or to anything for that matter.
The inside of the bag has two large pockets, one that is zippered.
also each side is lined with large and small elastic loops to store a multitude of things.
Plus another pretty cool feature is that the bag has a piece of cord that is adjustable and hold the bag open so it will sit nicely on a table like a workstation.
I purchased mine from here (http://www.joesarmynavyonline.com/servlet/Detail?no=8513
) but that model can be had from many different online stores.
