on saleJacques Herbin Bleu Des Profondeurs - 30ml Bottled Ink

It looks pretty dark with an extra-fine and fine nib, more so than a swatch of it - of course. Not as blue as Rue de la Verrerie.

A very good deep blue black ink. -with perhaps a bit of purple undertone too. I have this in a Lamy 2000 with a rather fat medium nib. This has been my go to blue for awhile. It’s a beautiful blue with authority.

I might be swapping it into my Pilot Custom 823 which has a much finer writing medium. then go with the Rue de Verrerier in the Lamy, it’s a more open blue by comparison. J.Herbin does a nice job with blue inks and the two mentioned are my favorites. They compliment each other nicely.

This ink despite being rather saturated and dark, I don’t see any issue with bleeding through on either Midori or Clairefontaine. A great blue a strong value

Very nice, rich color from this ink.

I have so much ink that sometimes I forget what I have! I rediscovered this ink in my collection and pulled it out to use in my Diplomat Aero Midnight Blue pen. Wow!! It's a lovely blue/black or very dark blue. It's wetter than average and flows really well. It doesn't really shade, but as it is a dark blue, that is to be expected. It's drying time is average on Rhodia paper. And the price is great. Great ink!!!

Herbin Bleu Des Profondeurs is a great deep blue color that works perfectly in professional settings.
