These are the latest pens from Michael's Fat Boy collection. Great pens made in America! These pens are machined from aircraft quality billet aluminum bars and hand crafted by Michael in the USA.
The GT-427 and SS-350 Cam Pens feature four machined cam lobes properly rotated to match the first four lobes (opposite the timing gear) on the popular cubic inch sized motors. The large lobe shape also provides a very comfortable grip for an everyday writing experience! A matching color rotating ball bearing stand in included with the purchase of a Cam Pen ($42 value)!
