Abit of a let down. i have been eyeing these pens for a bit, but not long after using one, the pen looses the boldness of it, and now it writes like its running out of ink. the ink window shows it full. i've even licked the ball, still writes like it is struggling. Sad because i really wanted to enjoy these pens, i love to write. i thought the product company would be good. i'll have to try another of their products to get a better opinion, but for these pens? they are cute, but i'd find another, unless money is no issue, then keep buying them to replace the previous ones, that run out quick.
