Set includes a RapidoSketch pen with stainless steel nib and refillable ink system and one 22 ml bottle of Rapidograph Ultradraw black ink in a rigid plastic case.
The versatile Koh-I-Noor Rapidosketch Drawing Pen handles like a pencil, moving in all directions without snagging or digging into the drawing surface. It's used to draw precise lines with an engraver's perfection and can handle a loose sketching style or a finely detailed pointillist technique.
Please note: Technical pens require special care, and the nib MUST be flushed out with water after every use to ensure that the ink does not dry in the tip. The tips are very delicate and should not be dropped on the floor. Technical pens have to be held upright in order to get proper ink flow. Tipping the pen to the side while working will result in a broken line.
Pen dimensions: Approximately 5.3 inches (13.5 cm) long, and 0.4 inches (11 mm) in diameter.
