These nibs are the best. ..these are not the same nibs you get stock in a uni or 311. These are alot harder but the flow of ink is great.so instead of your nib breaking down easily like the stock one this will stay hard and keep your pen lasting a lot longer.
This ink is the best. When i bought the black i tested it out on the sidewalk..over a year later its still there and barely faded. This ink is a must for freights and anything outside.it will beat the weather forsure
