Brow Artist Micro Tattoo brow felt pen by L'Oreal Paris Make-up offers easy to match shades for 48H naturally tattooed brow look. Its ultra precise & soft fork shaped micro felt tip mimics brow hair for natural definition. Start by brushing the eyebrow with an eyebrow spoolie, then hold the micro tattoo so that the points tip is parallel to the brow hair growth direction. Finally, draw light strokes in the same direction as the brow hair. Easy to match shades with a mistake-proof ink formula for 48H of defined brows.
