This Pen is a spirit level, a ruler, a screwdriver, a capacitive stylus and a ballpoint pen. The screwdriver attachment is stowed away safely under the stylus when not in use, and the stylus itself can be attached to either end of the pen so it doesn't get lost when you're busy driving screws. Twist the front section to retract the refill when not being used for writing. Hexagonal barrel won't roll away when not in use and is comfortable to hold when writing. Delivered in a box.
