New in box USB rechargeable make up brush cleaner and dryer. Clean your brushes and use them in a matter of minutes. Great for people that have acne and that wear make up every day. I seen a huge difference in the way my make up goes on and my clean just being so clear from always using clean make up brushes. No more batteries just plug it in the wall or your laptop and let it charge and use it. I use all my Chanel and Bobbie brown brushes with the kit
