Who'd have thought it? A fibre tip pen that's refillable with an international standard ink cartridge? That would be a Yookers. Oh, and you can replace the nib sections too!

All you need do is select the Yookers pen that takes your fancy, and if you want something other than a 1.0mm tip, you can customise it with the tip size of choice before selecting pretty much any colour of ink you like, from many different brands.

The Corus is classically-styled, with a sleek lacquer barrel and snap-on cap. The barrel unscrews so that you can fit the ink cartridge, but this is also all that's needed to swap in a different-sized nib section.

It's fitted with a robust 1.0mm tip, the shaft of which is protected by a steel sheath, and is supplied with an ink cartridge. It will also take a converter for use with bottled ink.
