Diplomat Aero Rhomb Flame Fountain Pen
The Diplomat Aero Rhomb Flame offers a bold new interpretation of the Aero collection, replacing the iconic Zeppelin-inspired grooves with an intricate rhomb-pattern guilloché engraving. Precision-crafted from stainless steel, each pen is individually hand-torched to create a stunning spectrum of blue, bronze, gold, and violet hues. The flame treatment gives every writing instrument a unique appearance, ensuring that no two pens are exactly alike.
The fountain pen is equipped with Diplomat's smooth-writing stainless steel nib, delivering exceptional precision and reliability. It fills using a standard international cartridge or converter (both included) and features Diplomat's patented Soft Sliding Click cap mechanism for a secure closure and a smooth, satisfying action. The Aero Rhomb Flame collection is also available as a twist-action ballpoint pen, capped rollerball, and 0.7 mm mechanical pencil.
Handcrafted in Germany since 1922, Diplomat writing instruments are renowned for their precision engineering, exceptional quality, and timeless craftsmanship. The Aero Rhomb Flame combines innovative guilloché engraving with a hand-applied flame finish, creating a distinctive writing instrument that is as unique as its owner.
