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 Nikaa. I remember the ink performed very well in her Sailor 1911 nib and I expected the same in my pens. The ink delivered. It flows nicely and is quite vibrant. Drying time is reasonable and the feel, even in finer nibs, is pleasant. I haven’t observed any unproper behavior. It just didn’t like water, that’s all.
