Ultra-low viscosity ball pen - these write like butter!
Ballpoint pens in the past used "sticky" ink, but Anterique's oil-based ballpoint pens use "ultra-low-viscosity ink" (Mach ball ink). Ultra-low-viscosity is ink that is "smooth" and easy-flowing. Anterique ballpoint pens use a pen tip with a built-in spring to precisely control the flow of ink for a very crisp, non-smudging, ultra-fine .5mm line.
This pen is a big upgrade over your standard ballpoint. Not only does it write much better than a typical ballpoint, its thicker body is more durable and rattle free.
