Keep your pens close at hand with this slim pen case attached to your notebook! It features an easy-access pen pocket with a flap closure, as well as a larger zipper pocket and an adjustable elastic strap that can fit an A5 or B6 notebook. The strap slips onto the cover of your notebook, and it works with both hardcover and softcover notebooks. This case is made of rugged cotton canvas. To attach this case to your notebook, expand the strap as long as it will go, slip it over the cover of the notebook, then tighten the strap until it fits snugly but not too tight.
