Have you had it with traditional chalk that creates a snowfall of dust while you write? Chalk is the usual writing tool used by teachers in classrooms. It's easily erased or wiped off from chalkboards or blackboards, making it convenient for teachers to modify their work while teaching or writing reminders. The problem with plain chalk, however, is that it can leave clouds of dust as you write on your blackboard.
