Editing Jinhao (section)

===991===
The Jinhao 991 is a plastic/resin demonstrator fountain pen that is a near copy of a Uniball Vision rollerball pen. The pens are available in a variety of translucent colors, ship with twist piston converters installed, and fit standard international cartridges. Caps fit tightly and post well, but both cap and barrel tend to crack with time and use. The F nib is a standard winged nib, while the EF version comes with a hooded nib, but as the nibs and feeds are shared with other Jinhao pens such as the 992, some dealers will assemble 991s with EF winged nibs.
