Experience the quality and precision of Rotring drafting pencils with the recent 800 series. Undoubtedly, 800 is Rotring's top of the line drafting pencil. Unlike its cousins, this fine writer features a handy retractable tip. A twist of the knob at the back of the pencil deploys the tip, twist the knob the other direction and the pencil locks the tip so that the lid doesn't pop out while it's not in use, protecting your pocket. A variation of the 800 is the 800+ which includes a stylus. You can use the stylus while the tip is retracted inside the pencil.
