We don’t know who the stealth thief is who always steals our pen caps, perhaps the same dude who keeps removing one of our socks from the dryer, but we do know he’s killing us. The PuterPen was designed to eliminate the annoyance of misplaced caps. Available in titanium or aluminum and stainless steel, The PuterPen is a minimalist pen that cannot be separated from its cap. Despite not showing any thread, you simply rotate and slide the attached top down to use it and then rotate and slide it back up when you’re done. We’d suggest banks invest in a shit-ton of these.
