Unlock an infinite palette of custom colours for your pocket-sized writers with the innovative Kaweco Mini Foldable Piston Converter. Precision-engineered in Germany, this micro-syringe style ink reservoir offers a highly sustainable, eco-friendly alternative to disposable plastic ink cartridges. It gives you the complete creative freedom to draw and load premium bottled fountain pen ink directly through your pen's nib and feed system.
What makes this mini converter a true structural breakthrough is its ingenious retractable folding plunger rod. Traditional pocket pen converters have always presented a structural trade-off: when fully loaded, the extended plunger arm is too long to clear the interior barrel of ultra-compact pens. Kaweco solves this problem with an integrated hinge on the plunger rod. Once you fill the reservoir with ink, the upper half of the arm effortlessly folds down 90 degrees against the side of the body. This reduces the total length by nearly 20% and clicks into a secure built-in locking notch, completely preventing accidental ink discharge while in transit. Thanks to this space-saving mechanism, it is the first official standard international short converter designed to fit perfectly inside Kaweco's smallest writing instruments, including the ultra-minimalist Liliput and the iconic Sport lines.

【ABOUT THE BRAND】
Founded in 1883 in the historic university town of Heidelberg, Germany, Kaweco is one of the oldest and most respected names in the fine stationery world. Originally starting as a dip pen factory, the brand evolved under the ownership of Koch, Weber, and Compagnie (creating the acronym Kaweco) to become a pioneer in precision German engineering and classic industrial design. Over nearly a century and a half, Kaweco has maintained an uncompromising commitment to creating high-quality writing instruments that effortlessly balance vintage aesthetics with modern, on-the-go functionality.
Kaweco specialises in creating compact, travel-friendly writing tools under the guiding philosophy of "Small in the pocket, great in the hand." The brand is globally celebrated for its iconic Kaweco Sport series—originally designed in 1911—which features a signature, roll-resistant octagonal cap that converts a pocket-sized pen into a full-length, comfortable writer when posted. Beyond the resin and raw-metal Sport lines, Kaweco's world-class catalog includes the ultra-minimalist Liliput solid metal pocket pens, the ergonomic Perkeo starter pens, and the sleek, full-sized hexagonal Special series, alongside high-precision mechanical pencils and rich fountain pen inks.
