A multifunctional pen with a stylus at the end for using on touchscreen devices. But it gets better...The stylus tip unscrews to reveal a flat head screwdriver so that you can tighten glasses or undo screws with ease while out and about. It also has a ruler on the side displaying cm and inches, for quick measuring when you need. Also on the side of the pen is a spirit level, so that your hanging pictures can always be levelled and straight. And, of course, the pen has a retractable ballpoint tip for writing. Ink colour comes in black and blue, to suit you. The pen is made of plastic and aluminium and is 15.3cm long.
