Brand New Marc Jacobs The Crease Brush 24 is definitely a beautiful brush for blending color into the crease. The pointed dome shape is created nicely to concentrate the eyeshadow into the crease and turn on its side to blend. You can lightly apply shadow into the crease for a wash of color or pat the shadow on the crease to build it for an intensity. This brush picks up color very easily and disperse it without any difficulties.
