Have you tried this lovely mechanical pencil? I love the feel and weight of the pencil. Smooth writing and lovely colors! The eraser also rotates up and back down with light weight turns. Made in Japan.

The Tombow Mono Graph Soft Grip pencil is a comfortable drawing pencil with a handy twist up eraser, available in .5mm. The new soft grip feature makes the Mono Graph even more comfortable than before! The Mono Graph is also a shaker pencil, which means you can shake to advance the lead.

Tombow Japan says this about their pencil: “The MONO Graph Mechanical Pencil features an innovative shake-mechanism that allows the user to extend the lead by simply shaking the pencil. The pencil’s clip is equipped with a shake lock that prevents accidental lead extension. A 4mm long fixed guide pipe prevents the lead from breaking and enables users to draw and write firmly, stably, and comfortably. Features one of Japan’s most popular erasers, the MONO Eraser ( rotatable ). Refillable lead and eraser. 0.5mm graphite lead. “
