Sturdy piece of kit, has two clear windows and a flap which has loops to hold pencils / pens, as well as a large pocket for the documents. Mine is currently sitting with all the bug-out supplies with local maps and other important documents

(My Own Review of the Product, Contains Measurements)

These bags are great, large enough for pretty much anything and they seam strong enough to survive a beating!

Has a nice shoulder strap and a very nice front button and latch. opens up to a clear plastic pouch on the left, another in the center with a length of fabric hanging over the plastic in the center section. In-between the left section and the center sections are elastic bands to keep maps and whatnot flat as well as one on each section that is Removable at the bottom to change its Location (Warning, These Are Elastic, May Lose their Elasticity over time).

The furthest right section has rungs for 5 Pens/Pencils with one holding the top of the drawing tool and one near the end, a leather block stops them from falling out the bottom.

It also has a set of rungs on the far right side (About 1.5 Times the Length of the Pen Ones Apart) for something, it also small pouch at the bottom with a single rung that's got a dome button Just above it.
It also has a small buttoned pouch on the left bottom of this section for something like a eraser or a pencil sharpener .

The Documents Bag also has a very large main pouch behind the center clear section. has enough room for a book akin to a A4 sized Atlas (Quite Large)

Thank you for the measurements! I wanted to buy this bag but was concerned that it might be too small for my books. Turns out that my books can fit in it, so I'm going to buy this bag real soon.

No Prob's Mate, Just stuff it when you get it as all the leather is quite Stiff

I just used some old Books for this for the most part, But Newspaper could also work
