Some rather portable pocketable pens have graced these pages in the past. But despite them, PicoPen is still the smallest and most discreet. Made of stainless steel, PicoPen measures in at 3.25-inches long and weighs just half an ounce — both small and light enough to hold its own on your keyring besides your keys and whatever other multitool you’re lugging around. Liberating the pen takes a simple tug to release it from the grip of the cap’s strong neodymium magnet. It uses common D1 multi-pen ink refills available at most office supply stores and also comes in a slightly bigger titanium version.
