1st reusable makeup removal system in the world. MakeUp Eraser is cruelty-free, & chemical free. Our cloth is made of a premium polyester blend that is antibacterial and acts as a suction to remove makeup when thoroughly soaked in warm water. Use the short side of the cloth to remove makeup in circular motions & the long side to exfoliate after. We recommend using the MakeUp Eraser in sections & washing about 1x a week. Machine wash before first use.
