Cleaning brushes set 3 in 1.
1) For cleansing your brushes use the inner surface. Make circular movements in the inner and then to the outter surface with grooves swipe the brush to leave out the excess amount of water.
2) The black sponge is used dry in order to remove any eyeshadow/powder residue from the brush in order to use it after again.
3) The white sponge is used wet. Dampen your brush and then use it to apply shadows or any other powdered product for better application, with more intense coloring result and longer duration.
