When you take off the top(left) the shield(top) is there to push/flatten the pigment down.
Loreal Infallible shadows have been compared to Giorgio Armani Eyes to Kill line. I have not tried them but from other reviews, pictures, etc they look very similar. I was pleasantly surprised by this product and will definitely be picking up a few more shades in the future. Loreal Infallible Eyeshadows retail for $7.99 at Walgreens.
