I bought a makeup airbrush about three years ago. I was never able to keep it really clean because I was scared to take it apart. Consequently, it was often clogged and I couldn't use it. I finally watched a few videos to learn how to take my airbrush apart and put it back together. Then I bought this nifty gadget of cleaning brushes and my airbrush is like new. It's very handy and I like that all the tools are on a key ring.
