I love brown inks in the fall. Diamine Sepia has been on my list of inks to try for a while now. I purchased my bottle of ink from Cult Pens.
Sepia is a yellow-brown with shading and a little bit of sheen.
There is some nice shading on the ink drops, but there is a little bit of dark brown sheen as well.
Dry time: 40 seconds
Water resistance: Low-medium
Show through: Medium
On Moleskine paper, which is not fountain pen friendly, there was a bleeding in all nib sizes, and a little bit of feathering. This is not an ink I would use on cheap paper.
I used a broad Pilot Vanishing Point on Tomoe River paper. The flow was nice, no issues there.
Overall, Sepia is well behaved and has some nice shading and a bit of sheen. The dry time is a little it long at 40 seconds. I like browns, but this one is just a bit too yellow for me.
