I like how they keep you engaged to curtail the items to your liking? The pros are you get to try something new every month. The pros are getting a sucky bag that basically gets tossed because you don't like anything. But then you can rate those products and never see them again, for now the service fits my needs.
This is great for contour, but please use a light hand! This is a very rich, warm brownie brown and it's easy to over apply. Make sure your applying lightly and in a well lit room so you don't look like you smeared chocolate on your face! Specially good for deep skin tones.
This concealer is very opaque and long lasting. You'll only need the tiniest amount to conceal your entire face. It will last a very long time, Ben with daily use. The only con I can think of is that it could be a little drying if too much is applied.
