We are making some magnetic dartboards at the moment for a really enthusiastic customer which is always nice.  The dartboards are made from iron sheet and we hear  that you can hit the dartboard from 16 feet with one of the magnetic darts.  The dartboards are 500mm diameter and are being supplied in a smart presentation box made by us.  The game has turned into something of a sport in the office.  You may have to be careful from a health and safety point of view - insurance claims mentioning magnetic darts are probably not that popular.  Anyway we are very glad we are making some people happy and would never cast aspersions on our customer's having too much time.
