Pen Type-C

One of the most notable purchases in the past few years for me has been this Pen Type-C by CW&T. It doesn't have the usual pen shape, but rather a flat style that doubles as a bookmark. The ink cartridges are readily available (Pilot Hi-Tec-C Coleto) in varying colors. I've taken this pen on multiple flights, and it doesn't dry or leak. This pen feels indestructible thanks to the grade 5 titanium that makes up its body. And the best part? Absolutely no branding.
