First off, I don't recommend ironing this bag, because it will discolor slightly. When it arrived, it had some creases and wrinkles from packaging, so I ran an iron over it. The fabric got a little lighter where the iron had been. This didn't bother me, however, because I planned to attach patches to it, anyway (so it would be covered).

Pros:
-Being able to carry a lot of pens/pencils (able to have multiple colors with me for on-the-go sketching)
-Lots of space
-Interior divided into three sections
-Hook clasp closure keeps bag from spilling open

Cons:
-Pen/pencil loops a bit narrow (difficult to insert/remove anything larger than a standard pencil, would have been better done in elastic)
-One of the dividers in the interior isn't connected to the bottom of the bag (items slip under it and jumble together)
-Adjustable "cushion" on strap mostly gets twisted and bunched around the strap (would have been better to just make the whole strap thicker)

Overall, this is a pretty awesome bag. It holds my laptop, a couple notebooks, wallet, keys, and a few other odds and ends well enough for school, but somehow manages to not feel quite as "heavy" as other messenger-type bags I've used. It's a simple, basic bag. It's inexpensive enough that I might try to do a little customization work on it (replace the canvas pencil loops with elastic and maybe add a water bottle holder to the side) without worrying that I'll break the bank having to replace it if I mess up.
