Nail polish doesn’t appeal much to me. It works for Eddie Izzard but he has genuine class.
Today’s invention is intended to appeal to people who want to wear such varnish but who can’t resist picking it off in unsightly flakes.
One would insert one’s hand into the slot of a varnish machine.
This would spray a code or symbol on your nail in a very tough varnish.
It would then apply a self-adhesive stick-on nail film in an opaque, contrasting colour to each of your fingers.
When you were later tempted to pick off the outer layer, the code would be revealed, potentially winning a big lottery prize by placing a call to the number shown.
