I thought these brow pencils were the thin type, but they're the triangle type. Unfortunately, the shape was too thick for me to create hair-like strokes toward the front of my brows. Also, I purchased the gray color thinking it would look more soft and natural for my black brows, but it was too light and looked a little off next to the rest of my brow hairs. Also, the product did not last on my skin as long as I would have liked. Maybe others would like it, but this brow pencil just didn't work out for me.
Side note, my pencil came in a different packaging than what the site's product image which I though was odd, but I didn't contact customer service because it had the same product name.
