Robert Oster Blue / Black

September 26, 2017

Robert Oster is new player in fountain pen ink market. He operates through worldwide network of wholesalers. The inks are sold in 50 ml PET bottles with a tightly secure twist cap. I don't know who makes the inks for the shop, but the colors look interesting and fresh. At the moment Robert Oster inks are available in billion colors - I lost track how many.

Sample of Blue Black was sent to me by Akszugor. The color is rather generic, but I liked this ink. It feels wet in my Kaweco Sport and the flow is very good. Lubrication could be better but the level we get is sufficient to enjoy writing. I wouldn't mind having more of this one.

NIce review! I really do like this type of b-b. Yes, I'm making things more complex than they already are... but this hue is sort of a middling thing-of-a-bob between a true blue-black (don't ask me to define that) and a very dark blue or midnight blue or navy blue, e.g. like one of my very all-time favourites... S.T.Dupont's Bleu Nuit / Dark Blue (Réf. 040111). Thanks for the hint!!

Yet another good and informative review. I've got some but not used it yet. Looks a good, standard blue-black as other comments suggest as well.

A small step for all mankind but a huge one for me.... this ink is available in a 50-ml cask but my above-mentioned Dupont comes only in cartridges (since about 15 years ago, I think).
