This liquid brush is a really fun tool for creating "smoke" nails, "marbled" nails, or any really cool water-colored effects. The brush can be filled with Isopropyl Alcohol to use with gel polish or alcohol inks, OR it can be filled with water to use with Wildflowers Art Paints.
The liquid comes out of the top of the black part of the brush, and drips down into the hairs (on the outside of the brush). Or you can use it on a palette to add some water. It's a handy little tool to have!
