SUR-FIT Natura Stomahesive Flexible Skin Barrier with Pre-cut Opening, by ConvaTec, is part of a two-piece ostomy system that offers a tan tape collar. As with many Stomahesive skin barriers, this barrier's plastic coupling ring delivers audible security through "clicking." As soon as you hear the snap, you can trust that your complementary ostomy pouch is securely attached. According to ConvaTec, the SUR-FIT Natura Stomahesive Flexible Skin Barrier With Pre-cut Opening is ideal for individuals whose stoma output is semi-formed to formed. This dependable skin barrier, additionally, offers a unique formula that allows it to adhere to both moist and dry skin. It firmly fastens to the area surrounding the stom, yet is incredibly gentle on the skin.
