The Rotring Tikky Rollerpoint pens have a free-flowing liquid ink that glides smoothly onto your paper surface. The special free-flowing design makes it possible to use 100% of the ink contents, with consistent line quality down to the very last drop. The needle point pen tip gives you a fine line, and the ink level window right above the grip area shows the amount of ink left in the reservoir at any time. Different ink colors available.
Pen dimensions: Approximately 5.5 inches (13.9 cm) long and 0.4 inches (10 mm) in diameter.
