What are the dimensions?
This brush is 7 1/2" long from tip to end. The base of the bristles is approximately a little less than 3/8" in a diameter and the bristles are 5/16" long at the shortest and 7/16" at the longest.
Get your brush wet, wipe the end of it against the edge of your water container, rub against your dry cake until you create a creamy consistency and then paint on the face/body.
