Nonsterile gauze sponges are ideal for wound dressings, wound packing and general wound care. Each latex-free sponge is made of 100 percent woven cotton. Clean, debris-free packing has folded edges to prevent unraveling. 12-ply sponges are also packed in a coated paper envelope to reduce fiber debris. Easy-open envelope is carefully sealed to prevent the intrusion of dust and contaminants.MIINON25212. NON25212. Medline Medline Non-sterile Woven Gauze Sponge.
