One bottle of nail polish is a so-so stocking stuffer. But a collection of 10? Now we're talking! e.l.f. cosmetics Goody Gumdrops Nail Set ($10) includes not-so-ordinary neutrals, statement shades, and sparkling toppers. The mini bottles of cruelty-free polish are as cute as they come, and since DIY manicures are going to continue well into 2021, this is one useful gift as well.
