Assura 2-piece closed is available with standard or extended wear adhesive barriers. The full range of barriers includes flat and convex light barriers, available pre-cut (already cut to size) or "cut-to-fit" (meaning they can be cut to achieve a custom fit). The full line includes transparent and opaque pouches, which correspond to the Assura AC and SenSura Flex barriers based on a color-coded coupling system. Thus, a barrier with a "red" coupling size must be matched to a "red" pouch.
