It’s no longer reasonable to allow your writing utensils to do single duty. These days, a pen that does nothing but write is a child’s toy. Actually, it’s even worse than that, because kids know better than to write by hand, what with all the voice recognition apps they have within arms reach at all times. That means pens are functionally useless. Let that sink in a minute. But not this pen, because it’s also several other things that can help the user accomplish something important. This is no gimmick. It’s a revolutionary tool, and the world will never be the same.
