I absolutely love MAC Paint Pots. You can wear them under eye shadow as a base (or to create different variations of color), or you can wear them alone. One Paint Pot that is perfect for both of these is "Bare Study," which is a shimmy, light gold/beige. It's very neutral but also amazing beautiful and luminescent. If I use a different Paint Pot on my lid, I always use Bare Study between the crease and brow. It really lights things up!
There are essentially no "cons" to this item unless you think the price may be too high ($25). I actually found Bare Study at the Cosmetics Company Store outlet, too, and I was thrilled! Makes it just a bit better in terms of cost. The pros are that it is easy to apply, has beautiful color and shimmer, and is very versatile. Just make sure (as with all Paint Pots) that you screw on the top completely, because these will dry out if not closed properly.
