Here is one coat of OPI's Rainbow Connection over three coats of Ulta's What a Maroon (before I added the final coat of What a Maroon).
What a Maroon on it's own, aside from having a creative name, is a deep red jelly. The formula is easy to work with and applied well. The polish is as I mentioned already very sheer. This is three coat plus a top coat and the nail line is still visible.
Color Name/Number: What a Maroon
Number of coats: 3
Top Coat: Yes
Free of Formaldehyde, Toluene, Dibutyl Phthalate (DBP)
Have you tried glitter sandwiches before? What do you think of them? I know I'm late to the party :)
Thanks for looking!
