The Medium Eye Detailer Brush is designed to create soft definition in the eye crease for a glamorous effect. The brush fibres are slightly longer than those of the Eye Shadow Crease Brush so you can tuck in colour on the eyelids with precision. Sweep colour at the crease from the outside-in for definition. Gently smudge liner at the lash line for a vivid smoky look. This brush works well with pressed, loose or cream eye products. This brush is made with synthetic fibres.
