The Lamy 2000 Mechanical Pencil, designed by Gerd Muller of the Braun Electric Shaver design fame is so revered that it is on display at the Museum of Modern Art, New York and has won countless design awards. Made from a lightweight, durable fiberglass-reinforced polycarbonate resin from Bayer known as Makrolon, makes it virtually break resistant. The mechanism to expel the 0.5mm lead is push button making it a single handed convenient operation. The Lamy HB lead is wonderfully smooth and generous, due to the presence of silicon. The solid steel spring-loaded clip is made from a single billet of stainless steel. Please note, the metal tip is non retractable therefore itandrsquo;s always better to carry the pencil in a pouch. The Mechanical Pencil has a z10 built-in eraser held by four clips with a three cm cleaning needle underneath its protective removable cap. 100% made in Germany. Lamy offers a 2 year global guarantee against manufacturing defects.
