Ultra-fine precision eyebrow pencil that creates natural, hair-like strokes for fuller, defined brows. The flat V-shaped tip lets you fill, shape and define with control, and the long-wearing soft matte formula glides on easily without feathering.

Ideal for building sparse brows, adding definition, or reviving faded permanent makeup and microblading between appointments. Available in three natural shades. Coffee Queue is a cool dark brown with no warmth, suited to dark brunette, chestnut and soft black brows.

This is a refill cartridge for the Karen Betts KB Pen, a refillable stainless steel makeup pen (sold separately). Click it into your pen in seconds, or swap in a Lip or Eye cartridge whenever you like.
