The Widest Range of Pens on the Planet!
The highest quality writing instruments on the planet.
The design of the Onoto 'Pi' pen was created as a celebration of the famous 'irrational number' and features the first 314 digits of pi after the decimal point etched to the barrel.
Made from high density acrylic, this is a satisfyingly robust pen, with the plain barrel nicely set off by polished sterling silver trim in the form of 3 cap bands, a pocket clip inscribed with a chevron pattern and the Onoto logo, and a cap button, also featuring the Onoto logo.
Fitted with a 18k gold bi-color nib, available in a range of sizes. Refill with widely-available standard pattern ink cartridges, or fit a converter (supplied with the pen) to use bottled ink.
Available with two weight options: 25g or 32g. Use the drop-down list to select your preference.
Dimensions: capped 144mm, uncapped 127mm, posted 166mm.
Supplied in a luxury gift box.
