Hancept Zero Mk2 Card Pen
Slots, keychains, clips — there are lots of ways to keep a pen handy. Few, if any, take up less space than the Hancept Zero Mk2 Card Pen. As the name suggests, it transforms easily from a flat, credit card-sized rectangle to a functioning hexagonal pen, and back again. In card mode, it measures 3.3" x 2" and just two millimeters thick, while in pen mode, it's roughly 3.85" x 0.47". It takes standard Staedtler D1 0.7mm refills, is made up of 54 interlocking components, and thanks to a build that incorporates aluminum alloy, stainless steel, and magnetic materials, it weighs less than an ounce. Available on Kickstarter now with deliveries expected to begin in August.
