Tombow Mono Graph 0.7 mm Neon Yellow Mechanical Pencil  (Set of 1, Noon Yellow)

This modern and stylish mechanical pencil is chock-full of cool features: Its shaker mechanism lets you extend the lead with a simple shake up and down. To prevent the lead from extending in your pocket or pencil case, you can lock the shaker mechanism by pushing up on the clip. The clip also acts as a conventional click mechanism, letting you extend the lead by pushing down on it. A translucent grip area lets you see the pencil’s inner workings. A long guide pipe gives you a better view of where you’re writing or drawing. The popular Tombow Mono eraser is installed at the top with a convenient twist mechanism and usable length of approximately 0.7 inches (1.8 cm).
