This is a wicked prank first thing I did was get my boss and he fell for it hook line and sinker. Then proceeded to prank the rest of my work colleagues ! It's bin worth its money ! Pen has also taken some hits as has been dropped on a number of occasions ...... But still working ! I now keep it on my desk, its the only one there so if any one sits at my desk they tend to pick it up. Funny enough it has never walked !!!! Brilliant pen as can be seen had lots of fun with it !
