Most Anastasia brow pencils include a built-in spoolie plus a wax-and-pigment formula designed for easy blending and smooth, even application.
Shades span blonde and taupe through soft, medium and dark browns (including chocolate and ebony), plus granite and specialist tones such as caramel, auburn, strawburn and ash brown.
Triangular (three-edged) pencils offer multiple edges: a flat side for shading and outlining, a medium edge for filling and defining, and a fine edge for hair‑like detailing.
They are described as water-resistant and long-wearing, with listings stating wear for up to 24 hours.
They use a micro-fine (0.1 mm) brush tip that mimics brow hairs, offering balanced ink flow and an ultra-thin, flexible tip for precise, hair-like strokes.
Product details list dermatologist-tested and non-comedogenic notes for the pencils, paraben-free and cruelty-free labeling, and pen formulas that specify being free of fragrance, parabens, phthalates, mineral oil, alcohol, talc and gluten.
The triangular tip combines multiple functions in one: the flat side for shading and outlining, the medium edge for filling and defining, and the narrow edge for hair‑like detailing. Many triangular pencils also include a spoolie for blending to a natural finish.
When blended with a spoolie, pencils produce a natural-looking finish; micro-fine pens create realistic, thin hair‑like strokes for a lifelike brow effect.
