At that time, the popular writing utensils were mainly sold to young students. An inseparable bond between Kaweco and the students developed over the years. Dedicated to this bond, the Kaweco Student series was created, which is available with silver elements in black and transparent as well as in color combinations with golden details, nostalgic colors and soft beige.
