There are two very different ways of writing down information. One is on your phone or tablet, and the other is on paper. While using an electronic device is convenient, jotting down directions on your phone isn’t going to be of any use to you if it’s about to die. That means you will want to keep a writing implement of some sort handy, so why not get one that has a stylus attached to it? That way you’ll be ready for whatever situation life throws at you!

The Inka Mobile Pen and Stylus is a combination pen and stylus that is compact, and all on one carabiner clip that can be attached to your keys. It’s 4.25” long, and will work at any altitude or underwater. This $12 key chain is made of carbon fiber and nylon components, and writes in blue ink (the cartridge is replaceable).
