Staedtler pen with a high-quality metal nib of 0.2 mm writing thickness. Ideal for maximum precision in linear and architectural design. The package includes the body with the metal nib and one inkless cartridge.

The different coloring per size helps in quick selection for design thickness. The ink does not dry out thanks to the double sealing system on the cap, and the ink flow remains steady thanks to its collection system. Easy ink refill from a bottle or with a cartridge.
