Here is the Bag. I love the design!!
The inside is roomier than I thought. It can hold a small laptop (Macbook size for example) and several books or other stuff!.
It uses Velcro...but, I guess I'm fine with that.
Overall I'm pleased with my purchase! It's a very nice high-quality bag that I got for US $32.88 (Yes, that includes shipping!)
Finally, here is the illustration that was used for the cover. It is taken from the doujin artbook Petite Fatal 3rd by Windmail (An2a)
