The Super5 rollerball pen is a cartridge rollerball pen with a plastic body that is very similar to Super5’s more popular fountain pen.
The official name of the pen seems to be the “Super5 iR .7” as per the packaging, but this name isn’t used anywhere on retailer pages. The “iR” stands for “Ink Rollerball” which indicates that the pen uses fountain pen ink and cartridges.
