The Staedtler Mars matic technical pen is a high-quality drafting instrument designed for maximum precision. The professional equipment from Staedtler is especially designed for precise work, whether it be millimetre-exact planning of rooms or drawing one’s visions down to the last detail. With Mars matic, Staedtler offers a drafting instrument that also meets the demands of semi-professional users or students – with the highest level of precision.
The Mars matic pen features a hard chrome-plated drafting tube and colour indication according to ISO and DIN for easy identification of the different line widths. The double sealing system in the cap helps to ensure the ink does not dry up. And the ink collector system ensures steady ink flow. The pen can be used on drafting and tracing paper and on matt drafting film. The technical pen can be used with a compass and most lettering guides. It is easy to refill from a bottle or with a cartridge and there are a total of 7 line widths available. The drafting point can be changed quickly and easily. The box includes an instruction leaflet and warranty. The instruction leaflet shows how to fill the ink, change the drafting point and clean the drafting point. The warranty states - 'We give a warranty for the perfect function, and will repair faulty pens free-of-charge, provided the defect is not caused by normal wear or improper use'.
