Ohto Flat-C Pen

The Ohto Flat-C is a highly collectible metal retractable pen that was made in Japan. It’s no longer production.

The Flat-C is an all-metal ballpoint-style pen that used Ohto’s gel ink refill in a Parker-style G2 size. The original refill was a needlepoint one, which is common with Ohto’s ballpoint-style pens.

The model number of the Flat-C is the NKG-10FA-05. The pen was original sold in black and silver finishes and retailed for 1050 JPY, or about $11.

The Flat-C is a brass pen that is is finished with a silver or black coating.

The Flat name is a reference to how when you click the clip the pen refill is retracted, giving the pen a special feature you cannot find in similar pens, like the Rotring 600.
