It's a logo of Nail Polish. It is reduced to a small bottle with a brush and a cap on it. Inside of the bottle there is a substance people use to color and design their nails.
This Nail Polish icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,000 icons, all in the same style and quality.
