An auto-adjusting pen that's perfect for everyday carry

You don’t get to be called a pro if you can’t back it up. The Ti Pocket Pro proudly wears the title by accepting over  8̶̶0̶̶ ̶̶d̶̶i̶̶f̶̶f̶̶e̶̶r̶̶e̶̶n̶̶t̶ refills (we've since found they accept 100+) in a convenient and compact package. It’s not just about the sheer number of refills that work in this pen that make it peerless. It's about designing and engineering the pen to have them all fit perfectly inside without any hacks, mods, or voodoo.

The body of the Ti Pocket Pro seamlessly telescopes in length to accommodate different sized refills, while the auto-adjusting collet grip ensures a wiggle-free fit at the writing tip. Operation is as simple as unscrewing the body, popping in your favorite Parker or Rollerball style refill, and tightening it up. The design does the rest.

Great little pen

Really enjoy the small package and simple mechanism. Feels great and love that I can use my fave refill

Amazing pen

Use this pen in medical practice everyday. Fits perfectly in my scrubs. Love it! Not too heavy and unwieldy, and when I need a pen, it's right there. 10/10 would recommend!
