The Olight O'Pen Pro features a newly designed light on the pocket clip, as well as a green laser pointer. The controls of the light and laser are all found on the bolt, keeping the pen streamlined. This one is black. The bolt-action pen has an aluminum body that is capable of withstanding impact. When the ink eventually runs dry, the tip can be removed to switch in the included replacement or a compatible third-party replacement. The piece is finished off with a secure pocket clip, making this one of the best EDC pens on the market.
