Heavy-duty Comfee Sensor Sleeves are specially designed for easy-on, easy-off application! Made from vinyl that is stronger than comparable polyethylene sleeves, Comfees’ silky-smooth texture reduces friction to help sensors slide in quickly and easily. Offset top eases opening, while rounded corners and edgeless seams increase patient comfort. Tear-off seal allows for easy removal. 500 sleeves per box in size medium or large.
