Made from materials that will outlive us all, the ForeverPen is a super-tiny inkless pen made to hang-out on your keychain. Built to deliver more words than 500 standard pens, it uses a “silverpoint” tip, an ancient writing technique that works on all surfaces. It writes upside down, underwater, resists the elements, and even opens boxes. All while being barely noticeable—until you need it. A funded Kickstarter.
