The Brava Elastic Barrier Strip is designed to prevent the edges of the barrier from lifting and rolling and keeps your barrier securely in place. It is elastic so it follows body contours and movements. This can provide greater security and peace of mind that your barrier will stay in place. They are also skin-friendly as they absorb moisture. The strips are designed to stick around the edges of your barrier (overlapping onto your skin, like a picture frame around your barrier). You can use either one or two strips, depending on where you need extra security.
