Tombow OnBook Clip Friendly Mechanical Pencil - 0.5 mm - Turquoise Blue

If you've ever taken a writing instrument on the go, you know how important different attributes affect carrying convenience. The strength of the pen or pencil's clip, shape, size, etc. can all determine whether or not the pen stays with you by the end of the day. Tombow addresses exactly that issue with its handy-dandy (and don't forget friendly) OnBook line. Available as either a pen or pencil form, the OnBook features a strong, thin metal clip that is able to fit into narrow spaces.

The body protrudes a mere 2 mm above the clip so that it won't snag or hit things.

The body shape is slightly triangular so that it will stay flush against your notebook or book without rolling.

A variety of body colors in pencil and pen styles are available.
