These pens work okay once you get the sealant off the tip but they aren't the best pens I've ever used. I haven't had them long enough to comment about longevity at this point. Overall I'm satisfied with them for cost vs value.
I tried the sample pen in the store first and liked it. I bought the pack I just wish the assorted had at least a blue or black pen included. Pen writes great.
I went in to staples and found this was the new pen to try and fell in love with it. I am very picky with my pens and found this to be suitable. I started using it and it doesnt pass the highlighter test and it does smear easily compared to other pens.
