I forgot to post yesterday's review last night so you get two reviews today. Crimson is another red made by Robert Oster. I purchased my ink from Vanness Pens.
Crimson is a dusky, muted red.
In ink drops the ink looks a bit brown when pooled, but doesn't actually show sheen.
Dry time: 44 seconds
Water resistance: Low
Show through: Medium
On 20 pound copy there was a little bit of bleeding in the flex nib and some feathering as well.
I used a medium Pelikan M800 Renaissance Brown on Tomoe River paper. The ink had an average flow.
Overall, the ink is well behaved but I'm not crazy about the dusky color. I prefer my reds to be more vibrant. If you like the color give it a shot because it is pretty well behaved.
