The Kaweco Perkeo Iridescent Pearl M fountain pen reflects an iridescent mother-of-pearl sheen that changes color depending on the light. With a full 14 cm body made of high-quality resin, it features an ergonomic triangular grip and a medium M nib in silver-plated stainless steel with a pressure-closure cap. It works with standard international short or long cartridges and normal plunger converters. The iridescent finish in shades of pink, green, and blue gives it a magical and modern aesthetic, making it perfect for students and creatives looking for a comfortable and visually captivating writing instrument.
