The bag:

It's an ordinary army issue FAK bag, intended to be carried by the squad or platoon medic. It can be attched to a backpack, carried in a tactical vest or as shown here, in the included shoulder strap.
The bag is made from some kind of rubberized nylon and it's pretty much waterproof. The lid closes with velcro.

The bag opened.
Below: the contents.

Much of this was included in the bag when I got it, I added some things* though.
From top to bottom, left to right.
Small mirror.*
Roll of Bandaid.
Some tape. Usually there is some coach-tape there as well, but I used it up and will buy more soon.
Gauze pads. Two packs of five each.
Foam pad, used when treating blisters and sores on the feet.
Straps for attaching the bag to a backpack.
The box labeled 91 contains safety pins.
