Lip Brush: Some of you might be skeptical at first and think that a lip brush isn’t necessary. Well get ready to be persuaded. Cosbar’s lip brush allows for a smooth lipstick application and even has a pointy side that can be used for liner. This is amazing because this means you don’t have to buy a matching liner for your lipstick. It’s also great at getting the last drop of lipstick out of the tube so nothing is wasted.
