Sterile, rayon and polyester blend sponge is precisely fenestrated for easy and consistent application. Unique fenestration prevents puckering and allows the sponge to lie flat when wrapped around a drainage tube. Precut to eliminate the need for sterile scissors and save time. 6-ply, highly absorbent sponge is low-linting, fast wicking and provides all the benefits of a nonwoven sponge. Drain not included.
