Add metallic highlights to any porous surface with these beautiful polishes. The applicator is built right in. Just prime the applicator sponge by rinsing with warm soap and water then squeeze out excess water. Tap the sponge into the pot of polish and apply to your surface in a circular motion. The polish can be used to highlight or cover an entire area, using the sponge or even your fingers, a cloth, roller or even a stamp.
