The Kaweco Collection Sport Marble Ocean Fountain Pen Limited Edition 2026 brings an ocean-inspired look to Kaweco’s classic Sport design. Swirls of green and blue suggest clear water, deep currents, and sunlight on waves, creating a vivid finish inspired by the sea.

Each pen is made with a process that blends the colors directly into the resin, giving every piece its own marbled pattern. No two pens are exactly alike, and gold-plated trim adds a refined contrast to the cool ocean tones.

Compact and portable, the pen measures 10.5 cm (4.1 in) when capped and about 12.7 cm (5 in) when posted. It uses Kaweco’s German-made 060 stainless steel screw-in nib, available in Extra Fine, Fine, Medium, Broad, and Double Broad, with an interchangeable unit for easy customization.

The Marble Ocean Fountain Pen comes in a collector’s box with matching marbled artwork and gold foil embossing, making it a thoughtful gift or collection piece. It is part of the Kaweco Collection series and is available only during the 2026 collection year.
