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 \u201csilverpoint\u201d 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\u2014until you need it. A funded Kickstarter.
