Brow Pop Nano

Brow Pop Dual-Action Pencil has a dual-sided, triangular micro-tip with a thicker side to fill in sparse brows and a thinner point for shape and definition. It’s best for larger sparse patches, over-plucked or thin brows, if you want more of what you’ve got.

Brow Pop Nano Pencil has the smallest 1 mm point for the tiniest hair-like details and a soft, clean, natural look.  It’s best for the tiniest sparse patches, adding realistic details + a feathery effect. 

Both are super easy to use and long-wearing.

It’s an ultra-precise 1 mm pencil.

You can choose a shade based on what’s closest to your natural hair color. Or, take the brow quiz! It’s the quickest way to find your perfect brow products + shades. You can also DM us (@kosas) a makeup-free, filter-free selfie and we’re happy to recommend a shade.

Brush brows up with spoolie. Twist up nano tip until just visible. Without pressing hard, use a gentle flicking motion to softly detail. For larger areas, start with Brow Pop Dual-Action to fill + shape. Layer Air Brow Tinted gel and/or Air Brow Clear gel over pencil for the full Kosas brow look (peak tint, volume and hold).

No sharpening needed! The fine tip maintains its shape without dulling down or becoming brittle.
