The secret to flawless nails without leaving the house? It's this option from Manucurist. What makes the Green Flash kit particularly unique are the plant-based formulas that deliver a gel-like effect to nails with wear for up to 10 days. The brand also offers the set in tons of different pretty colors, all of which can be removed with ordinary nail polish remover. As T&C's Senior Digital Editor Roxanne Adamiyatt put it, the Green Flash set is a "game-changer."
