The Lamy CP1 ballpoint pen, crafted by Gerd A Müller—designer of the renowned Lamy 2000—reflects Bauhaus influence through its sleek, slender silhouette. Its name derives from its perfectly cylindrical form: "cylindric pen No. 1." This pen features a slim metal body measuring 9.5mm in diameter, finished in matte black lacquer and equipped with a brushed stainless-steel, spring-loaded pocket clip for secure portability.
