I've tried Sephora's Minx collaboration nail foils before, but now they're back and redesigned for Halloween. I really loved the perfect stars and night sky pattern set (although the skull and crossbones look cool, too), so I scooped them up and brought them back to Sugar HQ to try. Turns out they're a vast improvement over Sephora's initial batch of foils, so I'm really glad I gave them another try. To see the tricks I learned the second time around, just read on.
