MAC pro longwear eyeshadow keep your cool

My experience with the product : This is a “dark gray brown”. It’s a dark neutral gray with deep taupe-ish undertones. It has a satiny finish that has a bit of sheen to it but is by no means shimmery. Keep Your Cool gives nearly opaque coverage with little product and has wonderful color payoff. It feels very silky and blends very easily.
I mostly just blend it lightly on the lid or crease but it also looks wonderfully deep if packed on properly. This is also one of the shades that work on all skin tones perfectly.
MAC’s normal Eye Shadows contain 1.5g of product for $15, where Pro Longwear Eye Shadows contain 3.4g for $20… That’s over twice the amount of product for only $5 more and they’re longer wearing, so one of these will last
