The SenSura Mio Convex 1-Piece Drainable Ostomy Pouch is made of an ultra-soft neutral gray material that conforms to the body as it moves, and easily fits into hard to reach areas like hernias, scarring and skin folds. This product contains an elastic barrier which fits real body shapes and a full - circle filter for less ballooning. Light and direct pressure is applied to the peristomal skin to reduce the risk of leakage by allowing the stoma to protrude. Box of 10. Dimension: 11''. Volume: 655mL. Stoma Size: 1"-1/4 Pre-Cut, Deep Convex.
