Ah, a fellow "Tombow Zoom 505" enthusiast! In case you didn't know already, they have expanded the lineup somewhat. There is now a 0.9mm Mechanical pencil and a Ballpoint pen over and above the original 0.5mm Mechanical Pencils and Rollerballs[1].

There is also a new "Multifunction pen" (Black+Red+0.5mm) in three colours. It is slightly longer than the Mechanical pencil[2].

Finally, the Pentel Kerry makes a very good companion to the Zoom 505.

The Kerry is a must have for me; it got me through my maths degree. The simplicity of being able to close the cap and toss it in a jacket or jean pocket without worrying about pencil marks meant I always had a pencil on me and could write down things as soon as they clicked in my head.

Ah, a fellow Pentel Kerry user! I cannot stop singing its praises. I've one in 0.7, and one in 0.5, and between them they make good companions for my Uni Kuru Toga :)
