These pens are THE best pens that I've ever used. I've looked all over for pens that are smooth and inky without bleeding through the paper. I've tried Papermate felt tip pens, but those will bleed through your everyday lined paper, so that you can't really expect to write on both sides. These however have no such issue. The writing is smooth but not overly inky, so that you are only writing where you want to, and the writing is sufficiently effortless that you want to write because of them. They also don't dry out too easily, although I wouldn't leave them out overnight.
