Take your mineral foundation with you! This tool is a brush and mineral powder dispenser all in one. Made of pure pony hair, it also comes with a dial mechanism allows you to customize your application with three settings to control powder flow. This brush also has a cover top and a protective pull up sleeve to keep bristles in proper shape when not in use. This looks like something I want to try. It would probably fit better in my small case, so I can apply my minerals on the go, if necessary.
