Slip-Ease by Crosstex is a protective cover for x-ray film, plates, sensors, and positioning devices. In two sizes (small = blue, large = yellow), Slip-Ease can fit any size 0-2 film and sensors. It smooths the edges and corners of the devices and adheres with Crosstex's patented Safety Strip to prevent accidental aspiration. One Slip-Ease is durable enough for an entire mouth series; in addition, this universal cover protects phophor plates from scratching.
