Cross have a long history of making innovative and unusual products, along with their more traditional classic designs. The Edge is one of their more unusual and fun designs. It's an expanding pen - instead of pushing a button or twisting the body to extend the tip, you pull, as if you were pulling the pen apart in the middle. It extends out, and the tip springs out ready for use. You could start writing then, but there's a good chance you'll actually open and close it a few more times, because it's kind of fun to fiddle with. Supplied fitted with black gel-ink rollerball refill. Uses Cross Selectip refills.
