Elastomull Elastic Gauze Bandages are available in sterile and non-sterile versions. The non-sterile version is suitable for securing primary wound dressing and the sterile version can be placed directly on wounds. Elastomull is great for use on areas with constant movement such as elbows and knees. The elastic compression bandage is made of rayon and polyester, making it virtually lint-free. Elastomull bandages provide superior performance and stretchability in controlling bleeding or edema. Each roll is 4.1yds in length. Each version comes in 1", 2", 3" and 4" widths.
