The pen itself can easily be disassembled into cap, body, nib and cartridge/converter. Swapping nibs is simply a matter of unscrewing the nibsection and replace it with the alternative nibsection provided – very easy. The pen uses standard international cartridges or a converter, which is provided. The pen, as said, is charmingly chess themed, with a set of white pieces along the bottom of the cap, while both the cap and body have a checkered pattern to them. There is an attractive difference in texture between white and blue squares. Finally the cap has a clip, but it seems fairly flimsy and not solid at all – which isn’t problem for my intended purpose.
