I own the following white nail polishes: <br>
OPI - alpine snow <br>
Essie - blanc <br>
Orly - white out <br>
Sally Hansen Insta Dri - whirlwind white <br>
None of the above is even marginally useable (white nail polishes are notoriously difficult, you know that right? It's like they are deliberately formulated to apply unevenly). THIS ONE however is in a league of its own. In just two coats, it delivers both even coverage AND a smooth finish. No matter what you do or how poor your technique, it WILL apply evenly. Unheard for a white nail polish. <br>
This, along with Sally Hansen whirlwind white, are the only two white polishes (in my experience) that are acceptably opaque. I would stick with this though, the sally hansen one is barely of a liquid consistency and is thus impossible to use.
