The Curidas retractable fountain pen from Platinum introduces a new writing experience and technology. No need to worry about having trouble opening a cap when you have the other hand full and miss a chance to take a note on important occasions, which is one of the common problems seen with capped fountain pens. CURIDAS is a coined term created by combining the Japanese word referring to extending the pen tip CURIDASU and Curiosity. The new fountain pen was brought to life to fulfill people’s curiosity. Platinum Curidas Fountain Pen Prism Crystal is fitted with our precision Stainless Steel Nib. The package comes in a nice gift box with the pen, clip tool (for attaching and removing the clip) and 1 cartridge. Converter is not included in the package and needs to be bought separately.
