This is our deluxe line of non-woven sponges that are a unique rayon and polyester blend to provide improved strength andabsorbency. The increased material weight helps provide a more efficient sponge than our traditional Avant line by reducing the number of sponges that have to used for each procedure. These non-woven sponges provide increased wicking ability as well as less lint versus the traditional woven sponges (compare to J&J Nu-Gauze). Sterile.
