Beautiful Rusian ink for dip nibs, nostalgic brand from the USSR time "Raduga" ("Rainbow") - 2 bottles 70ml each of 2 colors - black and blue (or if you wish one of these colors). The colors are very beautiful and the ink very stable on paper and dries fast.
Please, DON'T USE this ink with FOUNTAIN PENS - they will get blocked forever. This ink is ONLY for DIP NIBS!!!
