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 Verde de Rio was sent to me by Akszugor. The color is fresh and nice. I like it a lot. The ink feels rather wet but, as most RO inks, lacks lubrication. There’s no water resistance.
