I love neon polishes and when you get good ones they are stunning, I was very lucky to pick up the full set of neons from Wikkid Polish link below as they are still available and even better on sale!
There are a set of 6, all opaque in 2 coats and no need to put white undies on!
I went a bit mad with testing them all in a crazy bright floral beachy summer mani. These stamped like a dream.
I used Sally Hansen White On in one coat for my base then all the neons for the stamping.
