This eye patch is designed with Flex-Form technology to create a custom fit for all different eye shapes and sizes. It has an updated formulation that creates a surface that re-positions easily, contours around the eye, and still holds firmly in place throughout the application process. Professionals love these patches because of their ease to work with and the time saved from prepping the eye. These lint-free patches have a smooth, coated back and will not shed lint that can interfere with lash application. It is a hassle-free application.
