Is there a difference between the regular Gold and Silver sharpie then the Metallic Gold and Silver Sharpie ?  I have no clue and havent played with either of the four but picked all four of them up the other day because I had some extra cash and they were on clearance for some reason at Wally world lol.  Figured I couldnt go wrong with picking all four of them up lol.  If nothing else they will sit in the pencil/pen/marker cup sitting on the work bench ha ha.
