Robert Oster's love of fountain pens resulted in the production of these inks, the contents and packaging of which are all nature-friendly. They really do reflect the vast palette of colours associated with Australia, which is why there are so many different blues!

Featuring the 4 basic elements, this collection from Robert Oster is made up of three standard signature inks and one Shake n Shimmy ink:

• Earth: Standard Signature ink in Brown
• Fire: Standard Signature Ink in a vibrant orange
• Water: Shake n Shimmy ink, dazzling blue in colour.
• Wind: Standard Signature ink in a grey blue. 

The Shake 'n' Shimmy inks from Australia's Robert Oster do just that: you give them a shake, the glittery bits within them shimmy and then the inks shine! Perhaps calling them 'Shake, Shimmy 'n' Shine' would have been better, but it's probably too much of a mouthful.

These inks are fine to use in standard fountain pens as long as you flush the pen through thoroughly after use, but they're not suited to vintage or particularly valuable pens. Dip pens or brushes are the safest instruments to use.

Each bottle contains 50ml of ink.
