If you’ve spent any amount of time reading Cool Material, you know how much we love a good notebook and accompanying pen for our EDC. There’s just something about physically writing things down with pen and paper that makes everything from notes and to-dos more relevant when they’re not stored in an app. Which brings us to the new MiniSwitch Pen. This perfectly tiny pen is meticulously machined from either stainless or brass to be the size of a pinkie when closed, while still converting to comfortable full-size in a matter of seconds with a clever locking mechanism. It attaches to your keys. It attaches to your zippers. It easily fits in the coin pocket on your jeans. It’s also perfectly balanced, built to last and designed to write in any condition (including zero gravity!) thanks to the Schmidt MegaLine 620M pressurized ink refill. Much like cameras, the best pen you own is the one you have on you, and the MiniSwitch Pen makes it possible to always have a great pen at all times.
