The ink colour Royal Blue is a medium royal blue fountain pen ink with medium shading and high copper sheen and a hint of purple – a subtle accent on paper. Kaweco ink is compatible with any fountain pen. 

Kaweco converters are particularly suitable for using the high-quality Kaweco inks from the ink glass.
