Since the establishment in 1911, the Sailor Pen Co. has been proudly maintaining its belief in the importance of precision writing instruments. Still today, they offer the discerning customer technical perfection and writing quality. This model – The King Professional Gear has a selection of 21K gold nibs (the same as on the King of Pens) and a unique design with a cut-away cap and inlaid Sailor anchor logo on the top.
All the nibs of the King Professional Gear are made of 21 carat gold, which gives them a very smooth feel on paper. The 21 carat gold, but also the polishing of the tip of the nib in iridium which protects the gold, make this large nib an exceptional piece in the world of gold nibs. In this size of large gold nibs for large pens, the fine size and sizes below do not exist: the length of the nib would make a FINE (or even extra-fine) nib too fragile.
In general, Japanese nib sizes are always narrower than European standards.
