This is a very cheap way for a beginner to get a few useful brushes which a very good quality for the price. I wash mine with soap and water every time I use them & they have retained their shape and are yet to shed a single hair. The stippling brush is lovely for applying powder & smoothing out foundation and the blush brush is easy to manage.
I personally don't find the eyeshadow brush very useful - it's too large & picks up too much colour. On the occasions that I've used it, I tend to end up with a mess. This could just be user error though so I'll give them the benefit of the doubt.
Best of all they come in a pretty little case to keep everything neat and together.
