Maybe use smth different, not just simple Black Circle :)
My suggestions:
	✘ - U+2718 HEAVY BALLOT X         (✘✘✘✘✘✘✘✘)
	✖ - U+2716 HEAVY MULTIPLICATION X (✖✖✖✖✖✖✖✖)
	✱ - U+2713 HEAVY ASTERISK         (✱✱✱✱✱✱✱✱)
And if you think, that circle is better, better use medium black circle.
It has better spacing.
