Infuse your handwriting with the tranquil depth of a moonlit sky using the Kaweco Fountain Pen Ink Cartridges (Midnight Blue). Tracing back to 1883 in a small shop near Heidelberg University, Kaweco continues over a century of German pen-making tradition, delivering exceptionally reliable, premium-grade ink in a clean, travel-ready format.
The Midnight Blue shade captures the subtle beauty of a clear night sky bathed in bright moonlight, offering an elegant, nuanced accent on the page that bridges classic blue and contemplative dark tones. Formulated to be water-soluble, non-toxic, and 100% vegan, this gentle dye-based formula lubricates the nib evenly for a smooth glide and effortless maintenance without clogging feed channels. Designed in the universal Standard International Short cartridge size, each cartridge contains approximately 1 ml of fresh ink, making refills quick and mess-free: simply unscrew the grip section, replace the spent cartridge, and resume writing instantly. Compatible with all Kaweco pocket pens—including the iconic Sport, Liliput, Student, and Perkeo series—as well as any fountain pen accepting standard international short cartridges, this 6-pack is an indispensable everyday carry staple for students, journalers, and professionals.

【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.
