It is a natural product made from real goat hair. It helps distribute the product evenly to the finest points in eye make-up. Due to its real bristle structure, it absorbs very little of the product to be applied and ensures that the product is applied to more skin, allowing the products to be used more economically. If the brushes are exposed to extra heat - the structure and bristles of the brushes may be deformed. Opened and tried-on products cannot be returned.
