Dritz - Clothing CareEach sheet attracts and holds loose colors in wash water so that clothes remain bright! The sheets are made from powerful fibers that soak up excess dyes in water. Once the dyes are absorbed, the sheet locks them away, protecting your clothes from being stained and damaged. Colors are prevented from running or bleeding onto clothes! Saves time by reducing the need for sorting or small or "light colors only" loads. 30 Color absorbing sheets in each box.
