The Mar-Med shower seal is a comfortable, easy-to-use, reusable waterproof protector. Just pull the plastic protective bag over your arm or leg and apply the neoprene velcro strap for sealing. It is a self-supporting garment which prevents the penetration of water to plaster casts and wound dressings on arms or legs during showering. It is simple and comfortable to use and will last through the average user’s duration of treatment. Also great for covering PICC lines in the hospital setting.
