What is a spoolie?

A spoolie is a makeup tool that looks like a mascara brush but has softer, finer bristles that are usually made of synthetic fibers. It is often used to groom and shape eyebrows by combing the hairs into place, as well as to blend and soften eyebrow color or product. A spoolie is also helpful for smoothing and separating eyelashes after applying mascara, creating a more natural and less clumpy look. Some spoolies have angled or tapered brush heads for more precise application, while others are larger for greater coverage.
