The antidote to boring nails. Inspired by Supergirl’s dog, Krypto, this pearly white nail polish is loyal, luminous, and always by your side. It’ll be your partner in shine through every adventure.

Up to 7 days of wear.* Smooth, glossy finish with brilliant shine. Pro-Wide brush for flawless application. Color remains true during wear. Smudge resistant. Dries quickly. *When used with our 3-step system.

1. Prep nails for proper adhesion: push back cuticles, trim nails, file to shape, buff surface, and clean thoroughly with 99% Isopropyl Alcohol or N.A.S. 99 Cleansing Solution. 2. Shake all bottles well to mix pigments evenly. 3. Apply Natural Nail Base Coat: paint the edge of your nail first, then sweep a thin layer across the full nail. Let dry for 1-2 min. 4. Apply Nail Lacquer the same way: paint the edge first, then sweep a thin layer of color across the nail. Let dry 1-2 minutes. Repeat step for a second coat. 5. Finish with Top Coat: paint the edge first, then sweep a thin layer across the nail. Let dry 1-2 minutes. Pro Tip: In a rush? We recommend DripDry Lacquer Drying Drops to speed up dry time!
