This is Essence's sand polish in Me & My Lover. I found it on Ulta's website for 99 cents, and tossed it into my cart during one of my last orders. I love textured polishes.
It's a pretty shade, totally worth the 99 cents. I wish it was just a bit more texturized though. I just checked it doesn't appear to still be on the site, but you might get lucky and find it in store.
