Hollister Premier - 12" 1-Piece Drainable Ostomy Bag w/ Lock n Roll and Filter (Convex CeraPlus-Cut to Fit) has an adhesive skin barrier attached to the pouch, which you cut yourself to best fit around your unique stoma. The CeraPlus adhesive wafer is infused with ceramide to protect the skin's moisture barrier. The flange is convex, making it ideal for ostomates with a recessed stoma. The pouch has a built-in filter to reduce odor as gas escapes from the pouch. The unique Lock n Roll closure system uses interlocking fasteners for a secure seal. This prevents output from leaking out of the bottom of the pouch during wear.
This particular Hollister ostomy pouch also has what is called a viewing option. There is a perforation line near the top of the pouch that you can tear to create a flap, which exposes a clear window. This allows you to view your output if needed.
