Lead and refill cartridges for mechanical pencils

Maintain the perfect precision of your fine writing and drawing work, avoid interruptions and write more sustainably with our high-quality lead and refill cartridges for mechanical pencils. A mechanical pencil (or mechanical pencil) is an indispensable tool for architects, designers, students and professionals who like a consistent, sharp line without ever having to sharpen. As soon as the marker runs out, you can quickly replace it with our break-resistant graphite markers. Our extensive collection offers refills in all common diameters: from the ultra-thin 0.3 mm and 0.5 mm for delicate details and mathematical formulas, the popular 0.7 mm for everyday writing, to the thicker 0.9 mm, 1.3 mm or even 2.0 mm and 5.6 mm sketch pens for artists and technical draftsmen. You will also find cartridges in various hardnesses – from the soft and deep black 2B for smooth sketching, the universal HB for general use, to the hard H or 2H for clean, technical lines that do not smudge. Manufactured from polymer-reinforced graphite for maximum elasticity and minimal breakage!
