The synthetic angled brow brush bristles are thin、 yet stiff to pick up、 deposit and spread your makeup with precision. For eyebrow grooming and blending、 so your brows no longer look like they are fighting each other! LOL.Even if you are not a fan of dual ended brushes、 this one is a must; the angled brow brush and spoolie go together like PB&J. Easy to hold、 easy to use、 easy to clean.
