It’s more convenient than their Hard Formula Eyebrow Pencil because it’s already in sword form so you don’t need to shave it but its formula is softer. Although it’s already in sword form, the sword edge is not as thin/sharp as you shave your own Hard Formula Pencil so the hair strokes you’re trying to draw are much thicker and more blunt. Color is not as natural and harder to control when trying to draw strokes of hair. It doesn’t last on the brows as long as the Hard Formula one. The volume of the pencil is much less so it runs out much faster. But to be honest, it’s a much better option than many other brands out there. Just the Hard Formula Pencil is still my 10/10 favorite.
