Add space between elements except the last one

Add space between elements except the last one

On this jsfiddle http://jsfiddle.net/k9Nhk/1/ you can see that I have 6
circles: 3 on the first row and 3 on the second row.
I'd like to add some space between them and was planning to use
margin-right: 5px. The issue if I do this is that the last elements
(circle 3 and circle 6) will also have this extra 5px to their right which
I don't want (since there's no elements next to them). Is there a
workaround to that?
What I' like is:
(Circle 1) 5px space (Circle 2) 5px space (Circle 3)
Thanks
