The newest addition to the Diplomat Viper range stuns in a bold emerald, green finish bringing a fresh twist to an already iconic design. Its precisely etched body mimics the texture of reptilian scales, offering both visual intrigue and tactile grip. Crafted from durable metal and finished with matching accents, this pen doesn’t just look premium it feels it. A smooth-sliding magnetic cap adds a satisfying, secure close to every writing session. Despite its luxe look and feel, the Viper remains surprisingly accessible, delivering exceptional craftsmanship at an approachable price point.

Beautiful looking fountain pen. Comfortable to use and provides a wonderful writing experience. Easy to fill, I'm using a blue black ink. I'd have no hesitation recommending this lovely pen.
