Big Idea Design continues their trend of innovation in the EDC pen game with the new Ti Pocket Pro pen. They’ve released quite a few fantastic pens over the years—many of which we still use on a regular basis—but nothing quite like this, because the Ti Pocket Pro pen expands to accept different cartridges. You can finally have a titanium EDC pen that accepts over 80 different refills of both the ballpoint and rollerball variety—without having to worry about gaps, hacks, modifications, spacers or tip-wiggle. The patent-pending design uses a telescoping mechanism that allows the pen to adjust to the size of the refill seamlessly and also accommodate the tip of your refill of choice with an auto-adjusting collet at the business end. Each pen is available in a stonewashed raw titanium or antique DLC (diamond like carbon) black finish and features a knurled grip and deep-carry pocket clip. It doesn’t matter if you’re a Parker, Kaweco, Pilot or Uniball guy, the Ti Pocket Pro is the pen you want for your preferred refill.
