Our undereye concealer brush. 5.75" long with a .75" tip.

Holding your brush with the bristles down (you don't want to get water in the ferrule) dampen bristles with warm water, and lather gently with mild soap or shampoo. Rinse under warm running water until the water runs clear and soap is thoroughly removed. Blot the brush well with a clean old towel (you may find that the brushes bleed a bit of dye the first time or two they are washed) and gently reshape. Allow your brush to air-dry flat.
