Tombow Onbook Mechanical Pencil

Tombow's unusually shaped Onbook Mechanical Pencil means that it sits perfectly against the outside of the spine of a book or notebook. The thin flat clip holds well so that the Onbook doesn't slide off. The thin profile of the Onbook means you can easily keep the a pencil with your favourite notebook without having to remember to pick one up.
