ProLongwear shadows (the originals) have such a great formula. They apply and blend beautifully and wear extremely well. I always use a primer but MAC claims these last even without a base or primer and one day, I may just put that claim to the test. Don't be fooled by how dark this colour looks. This is one versatile and very wearable shadow - as a fantastic crease colour or for a sophisticated smokey eye. You can smudge it around your upper and lower lash lines for a softly "lined" eye. Great value too - you get a huge pan (possibly too huge!) for only a few bucks more than the standard MAC shadow.
