Vertical Pen Test by Jens Clarholm

Jens Clarholm has been hard at work to find the best pen for his Circlon1 drawing machine.  The Circlon holds pens vertically as it draws, which necessitates pens that draw quickly and smoothly.  

You should definitely check out Jens’ detailed and thoughtful review.  For the sake of posterity, the winners were Pentel Energel Deluxe RTX and the Pilot G-2 07.

If you need to find the best horizontal pen for a drawing robot, you may find my review from last year helpful.
