It provides easy access to narrow spaces with its soft texture and small size. Ideal for powder foundation-powder and especially "baking" applications. Washing will be sufficient for reuse. Cleaning instructions: Do not scratch! Do not use boiling water! Do not throw it in the machine! Use makeup remover products, not brush cleaners. Wet the apparatus with warm water - apply make-up remover to the contaminated surface - rub gently - continue rinsing until the water runs clear. Then remove the water by gently pressing it - leave it to dry on a clean towel. As long as you keep it in a clean environment, you don't need to wash it every day. Traces of pigment may remain on it - this does not mean that the product is dirty. Since these products are sealed with heat, they will quickly become deformed or damaged if you abuse them.
