Robert Oster Signature Ink Review: Hippo Purple

There’s a new Robert Oster Signature ink in town, and this one’s a special edition. It’s called Hippo Purple, and it was made especially for the Hippo Noto Tomoe Notebook, a Kickstarter project.

The Hippo Noto Tomoe Notebook is a special sub-A5-size notebook (131mm x 208mm) with 500 pages of 68gsm Tomoe River paper. The creators of the notebook named it Hippo Noto because their late son’s favorite creature was the hippo, and “noto” means “notes” in Japanese. You can read all about the Hippo Noto Kickstarter project here. The project ends April 23, 2017, so if you’d like to support it, you’ll need to act quickly.

Robert Oster created a special Hippo-colored ink as a part of the Hippo Noto project. The ink has shades of magenta, ochre, and blue, creating a unique brownish-purple that mimics the color of hippos.

The ink is wet and writes quite well in my TWSBI Eco with a stub nib. It does not exhibit much shading with this nib and is a rather flat color. It is not waterproof. I did my ink testing on Maruman Septcouleur white paper (my usual ink testing paper), not the Tomoe paper that will be in the Kickstarter notebooks.

Although I was able to create some fun ink splats, this ink doesn’t have the gorgeous sheen I’ve found in other Robert Oster inks.

In wide nibs (I used a Pilot Parallel 2.4mm), the ink demonstrates subtle shading. I really like the unusual color.

You can order this special edition Robert Oster ink only through the Kickstarter project. So if you like this unique shade of brownish-purple, be sure to go to the Kickstarter page and pledge $47 for one notebook and a bottle of Hippo Purple ink.

(This ink was provided to Pen Addict at no charge for review purposes.)
