Beautiful Sailor King of Pen, with a Naginata Togi nib and urushi coated ebonite.
Amazing writer, as tested, out of the box. There have been very few nibs out of box that have given me pause due to the writing experience with the pen - and this is one of the few.
The creation of Master Nib Designer, Nobuyoshi Nagahara, this nib was created in 21K gold and expertly finished by the Sailor Master Craftsmen. There is a very limited production of Nagahara nibs and generally a very significant lead time to produce these pens.
