A replacement nib for the Rotring Radiograph pen pen bought separately. This replacement nib is 0.18mm. The Rotring Radiograph pen uses a unique capillary cartridge instead of a normal reservoir. The pressure equalisation system including ink helix is part of the ink cartridge so that every time the ink is changed you get a new ink helix. This means the ink helix never needs cleaning ensuring top reliability. Can be used on many surfaces such as line-board vellum drawing paper or tracing paper. Wear-resistant hard chrome-plated thin tip allows exquisite detail work.
