Few words can describe how amazing this polish is. Have you ever been so blown away by a polish that you can't stop staring at your fingers all day long and wishing that your work day would end?? Well, when you look at this polish it takes you away to a island beach with a setting sunset..... OMG don't we wish we were there right now.. LOL. Bombshell was made to be applied over the polish of your choice. We feel a BLACK BASE COAT shows off this polish at its best. Any other base color works with this topper as well, but might not have such a dramatic effect. This polish has a color shift from REDS, to PINKS, to ORANGES, to YELLOW / GOLD with that gorgeous rainbow effect as well. It has a high shimmer. Under certain lights it has a very cool metallic look! This polish also has holographic hex and square glitters that add that extra pizazz that every polish needs! THIS POLISH IS A MUST HAVE...TRUST US...YOU WON'T BE DISAPPOINTED!!!!!!! This topper only requires 1 to 2 very thin coats to achieve your desired look. Be sure to apply a top coat to seal in the glitter and allow for a smooth finish!
