Robert Oster Signature Motor Oil

Transform your writing into creative expressions with Robert Oster’s Motor Oil.

Handcrafted in Australia and inspired by the continent's vibrant colours. Robert Oster Motor Oil is a dark brown fountain pen ink with some green undertones, medium shading, and medium black sheen. It dries in 40 seconds in a medium nib on Rhodia and has an average flow.

Packaged in eco-friendly 50ml PET bottles from Australia's first carbon-neutral plastics plant, Robert Oster inks are 100% Australian-made and non-toxic. The highly recyclable PET bottle features a practical design with a wide mouth for easy filling and a secure, travel-proof cap. Shipped without a box, the bottles take up very little space, useful for those of us with so many different inks.

Each bottle proudly displays a cap label swatched by Robert Oster himself, ensuring authenticity and quality.
