I love this brush. At first, I wasn't quite sure what to do with it. I mean, it's a "weird" brush. At the time, I was into buying brushes and decided that I must own at least every brush type.
But, alas! My holygrail everyday brush. I use this to apply blot powder, my select sheer powder and powder blush. I love the soft hairs on this brush.
The base is packed while the tip is densely packed which allows for color achievement. It creates a flawless finish when used with powders and blushes, it deposits the amount you'd like without getting the color everywhere and using too much product. I think everyone should own a similar brush. It creates a very "finished" look. Of course, there are many cheaper versions of this brush, but if you can afford (40.00 USD) the price of this brush, go for it. It is money well spent.
Washing it gave me no problems either. The tips are white (hence skunk brush) and plain ole handwashing liquid or mild shampoo does the trick. A definite repurchase if I should ever need one.
