"What makes the Sparkle collection stand out amongst other colors in this genre is the pigmentation. The problem with glitter polishes is that if the base gets too thick with pigment, the glitter fades to the background or leaves you with a chunky, bumpy mess. So it’s a fine balance and Zoya has definitely toed the line."All Lacquered Up
"Overall, AWESOME!!! GLITTER!!!! It's like Zoya has been spying on all of us and seeing how excited we get about colorful glitters. I love seeing glitters in bold, vibrant colors. These definitely fit the bill for bold and vibrant! And they're uber-sparkly. I'd even say they're more sparkly than the winter Ultra-Glitters. I'm a happy camper."
