Kaweco Royal Blue is a washable ink for fountain pens. It could be easily washed out of the paper or erased with a special eraser. It also could be removed from clothes and different surfaces in case of any ink-related accidents.
Many brands offer royal blue inks. Kaweco's version, however, is slightly different — it has a barely noticeable purple undertone to it.
Kaweco Royal Blue dries pretty quick on most papers and has a good, moderate flow. It will work well in all fountain pens, new and vintage.
Each pack of Kaweco Royal Blue cartridges contains 6 Standard International Short cartridges. They are compatible with all fountain pens that work with Standard International cartridges. If you are using piston filler pens or pens with ink converter, you can get this ink in 30ml bottles or as a 2.5ml ink sample.
