This is the Mary-Lou Manizer from The Balm. It is kind of a multi purpose item. It is a great highlighter, but it works really well as eyeshadow too! I love when you can use the same product different places. For instance, today I used a bronzer as eyeshadow!
But I have to warn you! A little goes a loooong way with this product, so be careful not to apply too much! I find that a small stippling brush works really well with it.
