Let's file this one under "Just Plain Unnecessary".
Yes, I understand that some people have trouble applying mascara to their lashes and subsequently get black stuff on their eyelids or under their eyes. However, I'm thinking that having to hold the Mascara Shield with one hand while wielding your mascara wand with the other would make things even more difficult. Notice how the gal in the photo isn't applying her mascara and therefore isn't really demonstrating the usefulness of the product?
Plus, it's $7.50, and it appears only to be a dinky piece of plastic. My advice is to save yourself some dollars and clean up any mascara boo-boos with a trusty household staple - Q-Tips.
LMFAO
