Coloplast SenSura - 8 1/2" Closed 1-Piece Ostomy Bag (Cut to Fit - Maxi with Standard Barrier ) is made of a softer, stronger fabric that is more comfortable against your skin. The ostomy skin barrier works for stoma sizes between 3/8"-3". This is an opaque closed colostomy bag that can not be drained. The included filter helps to release gas which helps stop the bag from filling up and ballooning. Coloplast provides plastic bags to dispose of your pouch easily, even in public bathrooms.
