You mean Mad Minerals ?? Those are really good products. Barbie has great eyeshadows, and I really like their foundation. Currently they have a sale, so you can make a great deal.
I mostly buy their pigments and gel eyeliners. I really like this brand. The eyeshadow samples in jars will last you a long time, they are really generous and you usually get about two other free samples to try colors, which normally you would never tried, and I have to admit it works for me. When it come to full sizes, the jars are really packed and you will use your eyeshadows for at least couple of years.
