This mask can be used as a post-sinus surgery mask or as a base for various eye masks for maximum protection. The mask is secured in place using adjustable adhesive elastic leashes, adaptable to size and contours. When using the mask as a base tool for different eye masks, it is important to choose the same size for the mask and the eye shield. Both the mask and eye shields are color-coded - yellow for small size, red for medium size, and green for large size. The same eye shield can be used for both the right and left eye, as the shield will fit both sides of the mask. The mask is easy to install with an extremely strong closure using Trihook closure. The fabric is breathable and machine washable.
