I am very satisfied, the material is not heavy... it just requires careful handling because the layer is very, very thin. The eyes look great, you need to apply a little more liquid if you have dry eyes like me so they don't stick but synchronize with the eye. Nice result and it allows for the contraction and dilation of the pupil. For me, being brown-eyed, my pupil appeared in a stable size since brown with black looks black from afar. It may not work as intensely for someone with light-colored eyes because the blue/gray/green color might show a little after the pupil - unless your pupil is used to being dilated, in which case it will look black anyway. It gives the impression of a uniform white eye with a black pupil... it achieves the result! I recommend :)
