The most striking features of the Special Series are the simple, elegant and octagonal design with a snap button. Long and slim, made of ebonite and later of celluloid, the Special writing instruments have established themselves as reliable work equipment at a fair price. Due to the ball pens' great success, fountain pens and the small Special S version were soon added to the range. Exquisite aluminium or brass is used for production. Robust and reliable mechanisms complete the tasteful series.
