Robert Oster is new player in fountain pen ink market. He operates through retailers worldwide. 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 Maroon was given to me by Mmg112 – thanks!
The ink is rather nice but I’m not thrilled by it.
Drying time: rather reasonable. 10-15 seconds on Rhodia, 5 – 10 seconds on absorbent paper.
Clogging issues: None experienced.
Feathering: some experienced on Moleskine.
Bleedthrough: almost none.
Water resistance: this ink isn’t water resistant.
