The Stabilo Bl@ck roller ball pens were designed by Stabilo to target both students and professionals. This smooth writer produces a medium line, and has an anti-roll away design thanks to a small nub that sticks out from the pen body. The body also features a soft rubber coating and is ergonomically shaped for writing comfort. Different ink colors available.
Pen dimensions: Approximately 5.6 inches (14.3 cm) long and 0.4 inches (12 mm) in diameter at widest point.
