I tried a couple of these types of products – both disposable and reusable - to keep my eyeshadow from getting all over the underside of my eyes when I applied it to the top. It works well for that and for making a thin line of eyeshadow underneath. I don’t think it would work well for any elaborate eyeliner techniques, but to put on eyeshadow or probably to put on mascara without getting it everywhere, it worked great and it’s totally worth the money.
