Today's ink is Nagasawa Kobe #48 Water Source Marche, which is a hugely long name for an ink, so for this review I'm just going to call it WSM. I'm using this name because that's what my sample says, but according to Anderson Pens, the name is Suidousuji Marchais Blue, so two different names for this ink is confusing. First off, it turns out I stink at making letters with a paint brush, so sorry for the weird looking 48. Second, I spilled part of my sample while working with the ink, so I tried to make it stretch and totally ran out of ink. I got my sample of WSM from Vanness Pens. I appreciate that their samples are 4 ml of ink.
Water Source Marche is a medium turquoise with shading.
WSM looks amazing in ink drops. That pink sheen is gorgeous, but unfortunately it doesn't show up in writing.
Dry time: WSM dried in about 32 seconds in a medium nib on Rhodia paper.
Water resistance: WSM has low water resistance.
Feathering: WSM only feathered on Baron Fig paper, but did great on the other papers.
Show through: WSM had medium show through on all of the papers.
Ink swabs for comparison, left to right (or top to bottom for RSS): Diamine Marine, Kobe #48 Water Source Marche, and Robert Oster Torquay. I think Diamine Marine is the closest ink to WSM.
I used a broad nib on Tomoe River paper. I really like the shading this ink has.
Overall, I really like this ink. It does remind me of Diamine Marine, which I also love. I think they are close enough that you probably don't need both. I do wish I had a whole bottle of this ink instead of just a sample.
