My favourite brush of all time. The quality of the bristles is as of a high end brand. This brush applies the product flawlessly and blends out my powder real well. I love this brush and would repurchase it forever. Real technique brushes aren't too expensive, yet the quality is awesome. Brush is the orange one featured on the right.

this another one of the real techniques brushes, by samantha chapman of the pixiwoo sisters on youtube.

on with the review:
this brush is by far my favorite powder brush! (however, i do prefer kabuki brushes)
for the price, you can't beat it. it's soft, fluffy, and very dense (considering it's only $10). i find that i works great for both powders and powder foundations (doesn't give much coverage, though). the one thing that i don't like about this brush (and some other brushes from the collection) is that the larger brushes (powder brush, blush brush, foundation brush, etc.) are very large at the base. the purpose of this is so that you're able to simply rest your brush down on a tabletop for storage. personally, i hate this because i like to be able to put my brushes away, and this makes traveling with them a bit more difficult. however, if your into that, it's no problem.
i really love these brushes, and i cerainly suggest you give them a go.
hope this helped. x
