Liner 7mm/9mm

Liner 7 mm / 9 mm by Profi Nails is a professional double-sided nail art brush designed for fine lines, French manicure details, thin outlines and delicate gel designs. Two liner lengths in one tool give you more control: the shorter 7 mm side is great for precise details, while the longer 9 mm side helps create smoother, longer strokes.

This brush is made with quality talon pile, giving the bristles enough flexibility to glide through gel polish, paint gel and nail art products without losing control. It is a practical everyday brush for salon nail artists, instructors and students who want cleaner line work and more accurate detail placement.
