The back, sides, and closure flap of the case are in colorful, opaque material, and the front is clear PVC. The back of the case has a large slip pocket divided in two that fits a slim A5 notebook or two. The front flap closes with a metal snap. Inside the case there is a main A5 compartment that is gusseted to fit a decent sized notebook. Along the back inside wall are two clear pockets--a narrower one that fits small papers, accessories, or pens, and a larger one that can fit medium items like another notebook.
I think these are great for containing individual projects, and they're available in a lot of colors, so you can color code those projects. While they may look and feel a bit cheap, that's because they are, in fact, inexpensive, which is good, because you're going to want a few of 'em.
