This is a GREAT pen. I've used them for Fifteen to Twenty years(how long ago did they come out). I still have two Black ones and one silver one. I wear jeans all the time and I carry my Excalibur pen in my back pocket, which means it receives allot of rough treatment. The Excalibur(Black) I carry now, I've been carrying for close to a decade, it writes in the heat of summer(around 103) and the cold of winter(around 30 something). Yes I've lost a pen here and there, I'm actually surprised at just how long I've kept my present pen(it has a couple dents in it, but still writes just fine). If you want a pen that takes a beating and just keeps going this is the pen for you. Oh yes my silver one is in my Daytimer(my daily planner) Yes I'm an over the hill person(close to my 7th decade) but these pen have never let me down, and isn't that what we want a pen for. Now that I found how to get another pen I intend to buy one or two more. Hope this review helps you'll.
