I worked really hard on these formulas so that they wouldn’t only be beautiful in direct light. If you have purchased holos before, I’m sure you’ve noticed the lighter colors (when not in direct light) can have a grey cast to them. These maintain the brightness of the color, no matter the lighting. My holos are also a thinner base, I like a thinner base because they last longer on the nail, and dry faster. (Not to mention the bottle will last you forever!!) They can be layered over other colors to create your own custom holos adding dimension to any manicure. They are opaque on its own with two to three thin coats. I love versatility!
