The Sonia G. Brush Guide

Written by Kat Freitas-Seitz

“Masterpiece brushes.” “Breathtakingly beautiful.” “Truly works of art to create art with.” “Quality beyond your imagination.” “By far the BEST brushes I’ve ever used.” “I don’t know how Sonia does it—she is literally a magical brush genius.”

These are just some of the real (unsponsored!) reviews from makeup lovers who have fallen in love with Sonia G.’s cult-favorite brushes. When Sonia G. started writing about Japanese fude brushes on her blog years ago, she had no idea that a personal passion would turn into her own bestselling collection. Each brush is carefully designed according to Sonia’s exact specifications and crafted by skilled brushmakers in Kumano, Japan—the brushmaking capital of the world. Curious about Sonia’s brushes but not sure where to start? Ahead, we’ve put together a quick and easy guide to Sonia G.’s line.

Note: In general, makeup brushes made with dyed goat hair bristles should be used with powder products only. Brushes made with synthetic or undyed goat hair bristles can be used with powders, creams, or liquids.
