This very special Kaweco Sport is a pocket-sized fountain pen that shines an iridescent rainbow in direct light. The entire material is iridescent, not just a surface layer. Available in very limited quantites! This resin fountain pen has a very smooth steel nib and is a lighter weight to prevent hand fatigue. 

Iridescent Pearl is a limited production, part of the Collector's Edition. 

This pen takes a standard short international cartridge or a Kaweco brand mini converter. Comes with a blue ink cartridge.
