Why didn't anyone think of this sooner?
It looks like any other little spray can but this one is for your nails. It's spray on nail polish - genius!
Say goodbye to waiting ages for your nails to dry only for them to smudge anyway. Apply a base coat and when that's dry, shake the can and spray about 15 centimetres from your hand. You only need one coat and it dries almost straight away.
While it paints your nails, it also covers your fingers but once you've added your top coat and waited for that to dry, wash your hands and it comes right off your skin.
Spray it on a bit of cloth or paper to prevent your furniture getting painted too.
There are just a couple of brands selling it at the moment so look online.
