This product is part of a two-piece pouching system. The pouch is designed to be opened at the bottom when emptying. These pouches are most suitable for colostomies or ileostomies. To close the pouch, use the curved, beige clamp. The AF300 filter allows for a slow release and deodorization of gas from the pouch. Soft, beige ComfortWear pouch panels help provide comfort.
