The makeup brush accessory for the Brilliant® HydroSonic LUX Ultrasonic Machines (Sold Separately) is the perfect way to clean your makeup brushes. The silicone slots allows you to hold the brushes of various thicknesses and suspend them into the ultrasonic tank. Once the cleaning cycle is complete, simply lift up the insert on the lid and they will stay suspended over the tank to allow the brushes to dry while the excess cleaning solution will simply drip back into the tank. Works with the LUX models only (68-0130 & 68-0135).
