Coloplast® SenSura® Click Two-Piece Cut-to-fit Nonconvex Flat Standard Wear Skin Barrier with Flange and Belt Tabs 3/8" to 2-1/8" Stoma Opening, 2-3/8" Flange, Round, Large Coupling, Double Layer Adhesive, Audible Click-Lock Security Ring SenSura® Click is the new two-piece standard in ostomy care, offering a unique audible click-lock security ring. The patented click-lock technology provides the ultimate in security, convenience and simplicity with just a click to lock and a click to unlock. When the click system is locked, the pouch is securely fastened to the barrier. SenSura® Click has a double-layer technology comprising a darker skin-friendly contact layer and a lighter strong protection layer. The strong protection layer protects the skin from leakage and prevents the adhesive from eroding away from contact with stoma output. The layer in contact with the skin absorbs sweat and moisture. This helps to keep the skin dry and healthy, and reduces the risk of skin irritation. Flex patterns make the adhesive more flexible, thus giving greater wearing comfort as the barrier conforms to your body. The adhesive has a good tack and strong adhesion to the skin, providing security and confidence. Easy to remove.
