Robert Oster is new player in fountain pen ink market. He operates through ebay shop. 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 Orange Zest was given to me by Mmg112 – thanks!
The color of this ink is simply stunning. It shades richly but on some papers it may take a while to dry completely. It has no water resistance. Basically the ink is strongly saturated but rather easy to clean. This is a steady writing ink. It flows from the pens with no hard starts or gushes. I like it a lot.
