DESCRIPTION
The Pi Pen is based on the style and shape of one of the most famous fountain pens ever made – the Onoto Magna of 1937 which is still acclaimed by many as the best fountain pen ever made – this Pi Pen has 3 sterling silver cap bands with the sterling silver Onoto Chevron clip and the Pi digits engraved around the cap and barrel.
Hold the Pi Pen and you will marvel at its perfect balance and how tactile it feels – it is also one of the most robust pens on the market today, thanks to its durable, high-density acrylic composition.
The distinctive Onoto logo is carved into the sterling silver cap button with a frosted background, making it instantly recognisable, and a sterling silver barrel button finishes the overall luxury feel.
The Pi Pen is available in a limited edition of 314.
