This novelty pen will surprise anyone that tries to use it with a harmless electric shock. If you work in an office where colleagues regularly steal your pens, this is a great way to catch them out.
The pen seems to use the normal function where you press the top to reveal the ink tip. But beware - if you click on the top button, you'll get a shock, while if you twist the pen's base, a useable ballpoint tip will emerge.
(Note: As this item does emit an electrical shock, it should be used with care, and kept out of children's reach and not used by anyone fitted with a pacemaker.) |
