The easy-flow ink makes note-taking easy. I like blue best, but I buy them in mixed packs so I also use green, purple and red.
These pens are not good for filling out rebate forms; but when you're writing in normal size letters, the generous ink flow makes for very smooth and easy writing.
I don't know how to describe it, but this pen has a lovely "write." So smooth, it sweeps over the page. Unfortunately, the ink is not good on glossy surfaces and the tip is not fine enough for very small letters. Otherwise, a very elegant writing implement. Comes in lots of colors, including black (my favorite), orange, emerald green, and dark pink. There is even a "black-blue" for people who can't committ to one camp or the other.
