Take your writing to another galaxy with the limited-edition Kaweco DIY Sport Fountain Pen. This special glow-in-the-dark edition lets you assemble your own Kaweco Sport, making it as fun to build as it is to use.
Made from translucent green plastic with silver-tone accents, the pen glows after being charged in natural sunlight or under a UV light, making it easy to spot in your pencil case, bag, or on your nightstand.
Every Kaweco Sport is hand-assembled at Kaweco's factory in Nuremberg, Germany. With the DIY Sport, you get to experience part of that process by putting together your own pen from its individual components.
Choose from Extra-Fine (EF), Fine (F), Medium (M), Broad (B), or Extra-Broad (BB) nibs, all made in Germany. If you're not sure which to pick, the Medium nib is a great all-around choice. The pen comes ready to write with a Royal Blue ink cartridge.
Complete the look with optional Kaweco accessories, including converters, inks, and slide-on clips.
