I think everything in one, designed to stay in place and with a unique fit. Mepilex Border Flex is designed for a wide range of exuding wounds, such as pressure ulcers, leg and foot ulcers, traumatic wounds (e.g. skin tears) and surgical wounds. Mepilex Border Flex can also be used on dry/necrotic wounds in combination with gels. Mepilex Border Flex reduces post-operative blisters and can also be used as part of prophylactic therapy to help prevent skin damage, e.g. pressure ulcers.
