Gift Wrap
We offer a professional giftwrap service to complement your pen or leather journal. Simply check the giftwrap option on the product page before you add to basket (a charge of £3.25 will be added).
We use a premium silver giftwrap paper with a subtle two-tone patterned effect, and a hand tied silver ribbon. We also include a matching gift tag, which can be appended with a message of your choice. Simply add your message to the text box when you reach your basket. Items are giftwrapped individually i.e. if you order several items only the specific item requested will be wrapped.
We do not include any paperwork inside the giftwrapped item. If you select a different delivery name to your billing details, we add a gift receipt which hides all prices.
Nib size guide
- Distinct variance between nib sizes
- Free flowing ink
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.
