The Hollister New Image Colostomy Pouch is a drainable, Lock N Roll pouch that is easy to close which means simply roll it three times in the same direction, press from the middle out, and feel the seal. It is also easy to empty which means lightly pinch the sides of the leak-proof outlet for easy control of content flow (firm reinforcing strips shut as soon as you stop pinching) and easy to clean which means simply clean the inside of the pouch tail by wiping it with a damp tissue. *Two-piece Systems Do NOT Come with a Barrier
