Nail polish can be expensive, so imagine what we thought when we heard about China Glaze’s new Tranzitions collection, which technically speaking offers two polishes for the price of one. Here is how it works: Each polish bottle features a single color, such as Split Perso-NAIL-ity, a dusty pink/fuchsia combo, Modify Me, a periwinkle blue/indigo blue combo, or Shape Shifter, a violet/dark purple combo. When you apply the polish, it will appear as the lighter of the shades. When you then apply a top coat, the polish appears as the darker of the shades. As such, you can create patterns and prints on your nail with some clever top coat applications. To check out the Tranzitions collection, head to your nearest salon.
