Autmog 38 Twist
Canadian machined pen maker. The aesthetic and function make it one of my top picks. They make twist and side release click pens. One of my first pens that didn’t have any rattle.
Variants: Click & twist pens in a whole range of sizes, styles, refills & metals.
Refill depending on variant: Parker-Style G2, Pilot Brand G2, Pentel EnerGel, Schmidt 888 & Schmidt P8127.
