Libelle is the Latin word for dragonfly and this graceful insect is the symbol for Libelle pens. Libelle pens are high quality writing instruments made from unusual and eye-catching combinations of materials, including marbled resins, mother of pearl resin, and a unique high relief wire mesh resin. Deeply colored lacquer finishes and impeccable presentation are hallmarks of this innovative pen. The trim rings at the section and the barrel end have a Greek Key design. Fountain pen comes with cartridge or converter ink system, and the German iridium nib point is a medium width. Roller ball pen uses refills with extra capacity. All Libelle Nature roller ball pens use Schmidt refills, which are made in Germany and are compatible with Parker refills.
