Rotring Tikky Ballpoint Pen - 1.0 mm - Black Body

Overall, a nice pen - I really like the style, shape and feel of the body, while the refill is smooth and easily replaced. However, I have 3 of these pens, and the refill "clicker" on one does not work at all. A second pen's clicker works, but not as well or as smoothly as the third pen. Other than that inconsistency, it's a very good pen with a so-so click mechanism.
