The innovative line, with its unmistakably shaped clip, is a loyal, everyday companion dedicated to those who write for work, play or study. Few pens engrave as well as the Aurora Ipsilon Resin, making it a terrific choice for personal or corporate gifts. The Ipsilon fountain pen has a firm, gold-plated or stainless steel nib with your choice of M, F, XF, and B widths. Cartridge/converter fill with the converter included. The matching ball pen is pleasing to activate with its push-top cap. The fluid ink, capped rollerball rounds out the Ipsilon collection of writing instruments.
