I purchased my first brush. I bought some new mineral foundation so I decided I needed to buy a brush to apply it. It was not very expensive. It's called a high definition power brush. I believe it's by the brand Paris Presents. It's description is: "High-defintion is the latest technology in color cosmetics, developed for glamorous, picture-prefect results. This brush, with its tapered cut and quality design, works perfectly to give you that celebrity look every day."
I really don't have much to compare this brush to. I have used brushes that have come with products but they have never been anything special. I picked this one because it was really soft, and I thought a powder brush would be versitile though I don't know that I'll use it on anything other than the powder foundation I bought. It seems to work well. It picks up the powder easily and is very soft like I said. I would buy it again! It's fun to use. :)
