This brush is the size of your palm when in a retracted position. Yes, it is a small brush. Will ideally fit in small clutch or back pocket. Slim and easy to grip. It slides up and the brush comes out. Since the edge of the brush is thin and sharp, it can be used outline lips as well before lipstick application.
I'm in love with this brush. Totally travel friendly and reduces the need to use a lip pencil. One can easily apply lipstick using this brush.
