The first pen recreated in-house, the Bolt Action Pen v.02 offers all as did its predecessor, but with noticeably smoother action. In addition to design upgrades such as chamfered edges around the bolt track and a newly fitted thread with o-ring, the Bolt Action Pen v.02 now sports an INVENTERY signature emblem in gold or silver. Overall, v.02 offers nuanced design additions but, most noticeably, greater precision. If you own the first version, you’ll feel the immediate difference with this one.
