One of the bigger issues with most clickable ballpoint pens is that they are flimsy. Usually, the bodies and clickers are constructed out of cheap plastic and through repeated use they tend to break. If you are in search of a more ruggedized and reliable pen, there's the Karas Kustoms Retrakt. With an entirely metal construction it'll outlast any of the pens you accidentally stole from the bank. And since it is made to fit the popular Pilot G2 or Parker ballpoint refills, you'll be set for a very long time with this pen.
