El Corazon 421/5 Dalmatian is an Art Top Coat polish that contains tiny black matte glitter, and I'm pretty sure there's a bit of tiny gold glitter as well. They are all mixed in a clear base which makes them suitable for application over any color. 

The formula of this polish is really great, it contains a good amount of glitter which allows easy application and with a few strokes you get a full coverage of glitter over the nail.

The base of this polish is completely clear, which is great because you can layer it over any color, even over white - and get a clean look (there are polishes with a similar effect  that can look a bit "dusty" on the nail, but this one didn't).

For this look I applied one coat of El Corazon 421/5 Dalmatian over two coats of Seche Happy As Is, and topped it with one coat of Poshe.

I think this is a great polish that can upgrade any color, and it would be interesting to use it in a layering technique (such as jelly sandwich), or over pastel colors to imitate the egg birds look.
