Review: Robert Oster Signature Hippo Purple

This is Hippo Noto’s exclusive Robert Oster Signature ink. It is named Hippo Purple. At first I thought for an ink named purple, it doesn’t look very purple but Robert Oster Signature had revealed that the brief was for the ink to look like the purplish skin of an actual hippo. Thus, it doesn’t look overwhelmingly purple. Knowing the brief, I believe the colour fits well to its name.

Hippo Purple is a dry ink. It shades subtly. I recommend filling this in a wet pen. Hippo Purple is not quite purple, not quite brown. This is a truly unique colour that I’m having a tough time finding similar inks.

Review: Robert Oster Signature Motor Oil

My thanks to Glenn for the ink sample.

Robert Oster Motor Oil is a deep dark brown-green colour. And it looks just like motor oil or sludge. This is most definitely not my favourite colour. It looks like a very dark Pilot Iroshizuku Ina Ho. And it is giving me the Ina-Ho vibes. (I don’t like Ina-Ho.) It shades very subtly with a hint of lighter brown-green surfacing from time to time. It is probably best not to use it in a EF or F nib cause you lose all shading. Plus this is a relatively dry ink. It’s not my kind of colour but it is a rather unique ink.

Review: Robert Oster Green Diamond

My thanks to Glenn for the ink sample.

Robert Oster Green Diamond is a solid green, bright and strong. It does shade. It shades best with the 1.1mm stub nib. Robert Oster Green Diamond reminds me of Montblanc Irish Green. The green just pops right off the page. Though it isn’t my kind of green ink but green ink lovers do check it out.
