A must have with cloth diapers.Washable, Reuseable stay dry liners allows the wetness to go through to the diaper keeping baby's skin dry. Using Stay Dry Liners lessens the liklihood of experiencing full blown diaper "rash".This 100% polyester fabric does not absorb moisture. Stay dry liners catch solid stool so you rinse only the liner rather than an entire diaper. Helps prevent staining of diapers. These liners are amazing!!! A very worthwhile and time saving investment! We recommend 3 Dozen. Price is per DOZEN
