Try Michael’s Fatboy DetroitCams! They both feature four machined cam lobes properly rotated to match the first four lobes (opposite the timing gear) on popular cubic inch sized motors.
The large lobe shape also provides a comfortable grip for every day writing! Each pen comes with a matching color rotating ball-bearing pen stand. Each pen is a “Limited Edition” of 188 ballpoint/gel pens.
This is a matched number set of two of this unique Limited Edition!
