Platinum Fountain Pen 3776 Century Chartres Blue Rhodium This is a special edition, customized with a Ko-Dachi nib (Naginata Togi) from a Fine nib. I purchased it already ground, so I don't know the details, but judging from the grinding on the back of the nib, it's probably the work of Mr. Nagahara. - Converter included - Ko-Dachi custom (around NM) - Will prepare a box. Shipped via Takkyubin Compact. - Writing sample and enlarged image of the nib are included. The Ko-Dachi (Naginata) characteristics of "thin when upright, thick when laid down" are clearly visible. (Left: written upright, Right: written laid down) This is a very rare pen. Genuine Naginata nibs are quite expensive, so why not try this one?
