Nomadic PN-04 Snap Button Pencil Case - Yellow

This is highly recommended if you need to put a few pens and some office supplies in your bag. It doesn't eat up a lot of space, especially when you carry around a small bag. Another plus, it is definitely light-weighted. Avoid your supplies cluttered inside bag. Great to have!

I usually carry around 6 pens and pencils on the inside. In zippers, a 6 inch ruler, a stick eraser and white out. It holds everything I need very comfortably. If you need more than that, it does get a bit bulky like other reviews said (max might be around 14 pens/pencils on the inside). You could keep highlighters, markers, and pens/pencils in more than one of these instead of carrying everything in one big case, which I might do myself. I really like its sleek and simple design, and especially the snap buttons (velcro is loud). For my purposes, it's perfect.
