The formula was very easy to work with, especially for a holo, and only needed two coats. I think with a proper base and top coat the holo would have been even stronger, but as you can see, it was quite prismatic.
Indoors you can see the gorgeous pale azure and a more subtle holo.
UP Colors polishes are available at Llarowe and Ninja Polish. They have a great range of holo colors, so definitely check them out!
