Nobody could resist could resist filling in the lines on their composition (aka black & white) notebook. That was one downside of going spiral, they weren’t nearly as fun to doodle on.

Made of lightweight, tear- and water-resistant, expandable, and recyclable Tyvek®, it is constructed using a cool, stitch-less origami folding technique.
