ConvaTec SUR-FIT Natura - Durahesive Flat Moldable Skin Barrier has a mold-to-fit opening that requires no cutting, making it convenient to use. This flange attaches to the ostomy bag with a simple click. The center of the barrier features ConvaTec's Durahesive material, which can be molded around your stoma for a perfect fit. This also allows you to turtleneck the wafer up against your stoma. The material absorbs moisture and expands to protect sensitive stomal skin. The wafer features a hydrocolloid adhesive collar that resists moisture to maintain a strong hold. This product is ideal for people with liquid output.
