Marc Jacobs Beauty's 'The Smudge Brush' has short and firm bristles that are designed to ensure a precise and controlled application. Although it works well with any shadow or liner, we especially love how nicely it blends the label's Highliner Gel Eye Crayon into a perfect smoky eye. -Instructions for use: - Lightly dab brush in shadow or gel liner - Glide bristles along lash-line for precise application - Use short upward sweeping motions for a smudged or blended look - Use it with The Shadow Brush and The Crease Brush to create a perfect smoky eye
