Penbook | All-In-One SketchbookAccessories
Penbook was designed to hold your pen on the go, where you need it. There’s no need to search around the bottom of your bag or take the risk of ruining pockets. Penbook doesn’t have an extra accessory that attaches to your book to hold your pen – it keeps it simple. A molded pocket on the front cover provides enough built-in function to keep your pen secure and right where you need it.
