The flat palette is all magnetized on the inside, and you can put any makeup pans in it that you want. I mostly use NARS products in mine, I love that you can order a lot of the products in just the pan, ready to pop into the palette. I have it in small and large (you can see them in the picture at the top of this post).
Note: While all of NARS products are a great matte black, they get dirty the moment you look at them funny. The products in the picture above are actually pretty new, I think I’ve had the bronzer and blush pictured for only this summer! The pro palettes are no different. I only break mine out for travel, but the outside is all spotted. I just ignore this, they function very well and hold a lot of product.
Tip: The magnet isn’t great with MAC pans, but these disc magnets make them work and they’re still flat enough to fit in the palette.
This was just released, and I’m already obsessed! Expect a full post soon for just this foundation. It’s very easy to use, full to medium coverage. It is creamier than other stick foundations, so you’ll find it works even on dry skin.
