ConvaTec SUR-FIT Natura Pre-Cut Skin Barrier 413182 4.5 x 4.5 in 10ct

With an audible click to assure that the barrier and pouch are securely fastened together. It swells up a bit to protect the stoma, an effect called "turtlenecking", and its convex shape effectively treats retracted, recessed, or flush stomas. Highly durable defense against primarily liquid output, along with a gentle adhesive that keeps the item securely in place.
