This volcanic roller is crafted to be a splendid on-the-go oil-absorbing tool. It uses real volcanic stone to keep skin looking matte and flawless. With its naturally porous texture, the volcanic stone effectively wicks away excess oil and, unlike single-use blotting papers, is reusable and easy to wash. It is ideal for use on combination or oily skin for efficient oil control.This item cannot be exchanged or returned.
