Bought one last drop, thought it was the best pencil ever... boy was I mistaken. DO NOT BUY THIS! Breaks lead constantly, and now it will not push lead out of the tube. I've only had this for one and a half semesters. Sadly disappointed with my purchase... cheap $5 drafting pencil works better and I've had it for two years. The rotring sure does look cool though. And it's heavy and strong which I love, just wish it would work :(
