Today's ink is Robert Oster Rubine. Eventually I will get all of the Robert Oster inks reviewed, there are just a lot of them. This ink was provided to me by Vanness Pens for this review.
Rubine is a bright red with shading.
There is a little bit of brown sheen in large swabs.
Dry time: 25 seconds
Water resistance: Low
Show through: Medium
On Sustainable Earth 20lb copy paper, there was just a little bit of feathering, but other than that the ink did really well.
I used a Pelikan M605 White Transparent, medium nib, on Tomoe River paper. It had an average flow.
Overall, I think this is a nice red. It's not super saturated, but it's really well behaved, and has some nice shading and a little bit of sheen as well.
