I bought this yesterday and tried out today on my eyes for school. I love this product! It's so sparkly and perfect for New Years makeup. The only problem I have with it is that in order to have it be darker, you have to apply a darker base before applying it. It's almost like a glitter/pigment. I love it because it can go from normal wear to dramatic wear with just a base color.
I just got this product for under $3.00!!! This was well worth the price! I agree with the previous comment that there can be fall out . But all in all its a great product for a store brand. I apply my color over another black shadow with a base of course. Stays on all day. Absolutely love the shimmer.
