The Retro 1951 Big Shot is a slightly larger diameter Tornado. The realistically reproduced Sherman Tank is quite unique and arrives in a commemorative matching tube. The Titanium and Black Titanium are serious stunners. Fit, finish and fashion; another winner from Retro 1951. This capless rollerball features Retro’s signature knurled twist top. The rollerball can easily convert to a ball pen with a refill change to any Standard Parker Style refill. Color and point sizes choices abound.
