Since 1883, there have been various systems for filling a fountain pen. Today, ink cartridges are a widespread and popular filling method, but in the past fountain pens were mainly filled using ink bottles. Beside lever fountain pens and eyedroppers, the piston mechanism has been the most important and reliable filling system. In 1937, the Kaweco Sport Fountain Pen was first presented as a piston filler under the name #612, and it has been further developed in many different versions over the years.

Thanks to its clever compact mechanism, the Kaweco AL Sport Piston Filler holds an impressive (approx. 1ml) amount of ink. Piston fillers allow for an infinite choice of inks, as many inks are only sold in bottles, not as cartridges.  The pen can be refilled quickly and easily with the smooth-running refill mechanism. A transparent ink window allows you to monitor the ink level at all times.

The Kaweco AL Sport Piston filler has a matte black anodised aluminium body, which is durable and gives the pen a high-quality haptic. The perfect balance between the weight and diameter of the fountain pen ensures comfort during long periods of writing. Its matte surface contrasts perfectly with the shiny golden elements including a golden integrated clip - which enhances functionality with stylish elegance.

Kaweco is a distinguished German brand, with over a century of heritage in crafting fine writing instruments.  With their commitment to quality, innovation, and timeless design, Kaweco continue to captivate pen enthusiasts and collectors worldwide.

The Kaweco Sport was first designed in 1911 as a pocket fountain pen which could be carried everywhere. It featured an oversized cap which, when posted, turned a small pocket pen into a full-sized pen for writing. Today, the Kaweco Sport range includes fountain pens, rollerball pens, ballpoint pens and mechanical pencils.

The Kaweco AL Sport Piston Filler is available either as a ready-to-use Starter Set, complete with a 32ml bottle of Royal Blue ink, or on its own. The Kaweco Piston Filler is presented in an unusual round nostalgic Kaweco tin, which also features a place to stand the pen upright on your desk.
