This is a gastrostomy tube cover set. Type A, small size. The bottom fabric, which touches the skin, is a soft smooth knit. The middle layer is a 3mm thick domette padding. The top fabric is made of cotton, creating a three-layer structure. As this is handmade, there may be some slight variations, but it's designed to be about 5cm in diameter when worn.
