Haven`t tried their mineral foundation and I`m also curious to see how these are
but the mineral foundation brushes are just aamaazing their around $30 bucks synthetic material
coverage and blending: peerfect better than any mineral makeup brush i`ve tried the brushes a soft and provides a smooth application =)
i had some tested on my face last weekend in the city and the coverge was pretty good, but i didn`t buy any because they didn`t have my colour =( also my skin felt a little irritated, but i think that was more the brush she used than the makeup.
