I used to get these pens all the time because they printed bold, were waterproof, didn't skip, wrote smoothly and didn't stop writing till all the ink was gone. I don't know what they did to these pen, but they do not do any of the above now. The blue ink doesn't even look the same. I pretty sure they've changed the formulation of the ink. I think I bought 3 boxes. I tried several and never found one that was any good. Why can't manufacturers leave a good product alone!
