Glitter-packed polishes tend to be either too watery and translucent or have the dreaded "taco glitter" (which, according to nail bloggers, is perma-curly glitter chunks that won't be tamed by a topcoat). KB Shimmer manages to avoid these issues and produces some of the most unique glitters and duo-chrome polishes in the business.At under-$10 a pop, they're not much more than your drugstore favorites, but a lot more daring. We also love the brand's collaborations with die-hard nail bloggers, which always result in bold, on-trend shades.Nail Polish in Pigment Of My Imagination, $9.25, available at KB Shimmer
