From managing projects to working out some last minute calculations, having a little pocket notebook on hand is just the thing you need to keep every gear turning at your job.

At four by six inches, they fit comfortably in one hand or your back pocket.

Each 4-pack contains four different covers:

• Mechanical Engineering
• Software Engineering
• Early Computer Science
• Clean Energy

Each notebook has a different type of inside pages: (Lined, Graph, Dot Grid, and Blank), so pick the one that's right for today's field notes and you're ready for your next adventure.
