China Glaze in Celtic Sun (neon)
This is SO bright. When I saw it in the store, I had to buy them! It is like highlighter in a bottle. The woman in the store told me to put a coat of white under it and it very well.
The polish itself is very opaque, so white underneath was needed. If the white coat isn’t done, it will smudge and look all patchy, so wait until the white is 100% dry before using the yellow polish.
One coat of white + Two-Three coats of Celtic Sun + One coat of top coat
