The Kaweco Collection light blue F fountain pen is a special collector's edition that combines a soft glacial blue tone with precise fine writing. Made of high-density plastic in the iconic 10.5 cm pocket design (closed and 13 cm with the screw-on cap at the back), it features exclusive silver engravings and a fine F nib in stainless steel. It uses standard international short ink cartridges or a mini-bottle converter. The freshness of the pastel light blue finish confers exclusivity and contemporary style, making it highly coveted by collectors and pen enthusiasts for use in diaries and planners.
