The Design 05 from Otto Hutt is a compact, fully fledged pocket fountain pen or ballpoint pen for daily use. These writing instruments are equipped with a replaceable "touch tip" for entering text into smart phones or tablet computers. This lends an added variation to the functionality of this writing instrument.

Each pen is immaculately crafted from high quality materials and made entirely in Germany. As is customary with Otto Hutt writing instruments, every single utensil in the Design 05 line is individually numbered on the cap.
