The head is about a third smaller than the original with tightly packed bristles, so you can get close to the lash line as you like and create a thinner finer look whilst still simply sliding the brush over the eyeliner, and then 'walking' the brush along the lashline to apply a neat line of colour to perfectly define eyes. Thicken the line as you reach the outer corner of the eye for addition depth of colour and to widen the look of eyes.
