Ink Review #240: Robert Oster Moss


It's the first day of green week! This week is focused on all things green and inky, so today's ink is Robert Oster Moss. I purchased my sample of ink from Vanness Pens.


The color:

Moss is a dark green, and well, mossy.


When the ink is pooled it turns black around the edges, but it isn't sheen.


Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 25 seconds

Water resistance: Low

Feathering: None

Show through: Medium

Bleeding: None (except a little in the swabs)

Other properties: Medium shading, no sheen, and no shimmer

On 20 pound copy paper there was quite a bit of feathering but other than that the ink behaved well. 

Ink swabs for comparison, left to right (top to bottom for mobile RSS): Robert Oster Eucalyptus Leaf, Robert Oster Moss, and Diamine Classic Green. Click here to see the Robert Oster inks together.


Longer writing: 

I used a broad Pelikan M805 Ocean Swirl on Tomoe River paper. The ink had an average flow. There weren't any flow issues.


Overall, it's pretty well behaved, like most of Robert Oster's inks. The color isn't my favorite, I think there are lots of other Robert Oster inks out there that I like better. Give it a try, you might love it.
