Pen lovers will flip out over the Nomadic Roller case. As the quote on the tag says, it allows you to “Store your important pens individually.” The inside of the pencil case acts like a scroll that you can roll out to reveal 5 pen holders and two small compartments. It is designed to protect all of your writing instruments. The roll up style will keep your writing instruments from banging up against each other and your pens will be held securely in place by the pen holders. The case provides good visibility of the different writing instruments once unrolled. It is made of sturdy nylon material. Outer bag measures 2.5 (width) x 8 (height) x 2 (thickness) inches.
