Private Reserve Bottled Ink in Cosmic Cobalt - 60ml


Renowned for their vivid colours and highly saturated ink, Private Reserve Inks are one of the oldest fountain pen ink companies in the USA. Based in Central Indiana, they are regarded as a high quality ink manufacturer and their products come in a generous 60ml bottle with a wide neck for easy filling. This Cosmic Cobalt shade is a vibrant royal blue.

  • It is recommended not to use Private Reserve inks in vintage fountain pens as the ink can stain due to the high saturation of colour
  • When using Private Reserve inks please take extra care not to leave in your pen for too long to prevent clogging
