The writing instrument The fountain pen of the Liliput series is one of our smallest writing instruments. Concerning its color, the stainless-steel body is equally as striking as the mesmerizingly shining plumage of different hummingbird species. They get their colorful appearance due to the surface structure of their feathers, known as the phenomenon of interference, where light is reflected. Reminiscent of this play of color, our Kaweco Collection Liliput Kolibri gets its metallic shine thanks to the PVD-plating, a process resulting in various unique color combinations, making each fountain pen one of a kind. The nib A special highlight of this Collection variant is a laser-temperature-treated nib that shimmers in rainbow colors. The packaging This exotic variant comes with a silver tin box wrapped in a color-matching paper sleeve.
