This won't be a full review, just some quick first impressions of the inks I just got in the mail from The Writing Desk. Check this site for better reviews of the same inks. I've based my purchase on your opinions
Visconti Blue (in a Van Gogh bottle, i.e. the cheap bottle): Pretty wet but okay. Slightly slow to dry. Very subtle tone variation. Very full blue colour. I don't have too many blue inks, but it's by far my favourite: it looks very luxurious.
Diamine Umber: Very good flow, no problems, easy to write with. My first green ink, purchased based on the discussions here. It has a mossy hue which is quite nice and stylish. Very little colour variation.
Diamine Dark Brown: The laugable name aside, this is a very comfortable ink to write with, like the Umber. It's a nice soft brown with beautiful colour variation. The first brown I ever wrote with, and I loved it until I wrote with the next ink
J.Herbin Café Des Îles: Also a very comfortable ink to write with, possible even more so than the Diamine inks. The reason is that, while it writes as smoothly, the line seems a bit more controlled. I can imagine the 2 above Diamine inks would feather on cheaper paper and the Café Des Îles wouldn't. The colour is much deeper than the Diamine Dark Brown and the colour variation is spectacular. Overall, I'm very impressed with this ink.
J.Herbin Poussière De Lune: Pretty wet flow, but okay. Like the Visconti Blue, I have to watch out my nib isn't too wet and my converter isn't filled all the way (seems to give a bit too much pressure). Very little colour variation. My first purple, it's a very nostalgic colour. I like the way it's unusual but subdued: it's not a colour that will make people go "wow" but it will still be noticed as not being any average ink.
Conclusion: I love all of these inks
Next week, I'm expecting another shipment of inks, this time Rohrer&Klingner and De Atramentis. And nope, no extra pens yet to put all of these inks into
