The Original MakeUp Eraser is a premium, patented, polyester cloth made up of millions of tiny hair-like fibers that work together to create a "suction" for all dirt, makeup, and oil in your pores with just water. Double-sided to erase makeup with the short fiber side and exfoliate the skin with the long fiber side. These reusable, machine-washable cloths last 3 to 5 years and take the place of 3,600 makeup wipes.
