Once in a blue moon, you might come across a subtle shimmer fountain pen ink. It might seem like an oxymoron, but with Oster's Blue Moon ink that's exactly what you get- a well saturated bright blue ink with blue shimmer that really stands out when it catches the light. You gotta see it to believe it!

Robert Oster Blue Moon from the Shake ‘N’ Shimmy collection is a saturated medium blue ink with medium shading, low pink sheen and blue shimmer. It dries in 40 seconds in a medium nib on Rhodia and has an average flow. Robert Oster ink is made in Australia.
