Discover the wonders of the sea Get ready for a real treasure hunt with the new Kaweco Collection Fountain Pen. The Marble Ocean combines dynamic green and blue hues, mirroring the ocean’s large variety of colors, with fluid ease. Crystal-clear turquoise water, cerulean ocean depths, and fluorescent wonders from both wildlife and flora, the limited edition Marble Ocean draws a current of inspiration from all of them. Sure to make waves This summer delight is created with an inventive manufacturing process, every single fountain pen is made unique due to its one-of-a-kind color gradient. Like hidden treasure under cool waves, the gold-plated nib, with its warm undertones, compliments the rest of the pen. This pen has a medium nib. You can easily change the nib if desired. All nibs and the entire fountain pen are Made in Germany. Ready for immediate use, the writing instrument contains an ink cartridge in Royal Blue as standard (note: it is in the body of the pen, check before using). The light ABS material makes the pen feel almost weightless, making it effortless to write fluidly for long durations. Pocket-sized treasure This sport pocket-sized fountain pen only measures 10.5 cm when closed, making it very easy to take with you anywhere. With the cap attached, it grows to an average size of 12.7 cm which is very comfortable when writing.
