Highly specific tool for managing eyebrow shape and hair length. The scissors are top quality, perfectly shaped, sharp, and show no signs of sticking. The brush is necessary though less well made. As with any good brow grooming routine, always snip one hair at a time to keep from over-trimming/plucking. Brush the inside half of the brow up to clip stray or long hairs; brush the outside half down. Tweezerman gives you just the tools to be able to do that effectively. Highly recommended.
