The acid-etched armadillo shell pattern has this tactile bumpiness that I keep running my thumb over, way more fun than a smooth barrel. It glides across paper smoothly and the rollerball tip lays down a solid line without any skipping.

Picked this up at the Dallas Pen Show and the acid-etched armor texture feels great under my fingers, way grippier than I expected from a rollerball. It's a fun little pen that writes smooth and gets comments every time I pull it out at meetings.

The acid-etched armor pattern has actual texture you can feel, not just a printed design. Ink flows smooth right out of the box, and the rollerball tip doesn't skip even on cheap paper.
