The split compact is magnetic (like Terra Inca). There is also a mirror in the top portion.
But really, how could I doubt Guerlain? If they can't do anything else ... they can do a bronzer like nobody's business. They have the concept of 'enhanced' skin down to a fine art. And they do NOT disappoint with this product.
Each color shows up very well on my warm skin tone, both separate and blended together. Observe...
One thing to note is that the shimmer factor is controlled. There is some shimmer, but it's very subtle. You can use the bronzer, or any of the colors alone, or blend them together for a warm pink-bronze blush color.
I love this product. From packaging to performance, it really delivers.
