Sonia G Worker One is a brush that retails for $36.00.
Sonia G. Worker One Brush ($36.00) is a larger, denser eye brush that's is made out of dyed Saikoho goat hair, and it was intended to be an "eye blending brush" that can "soften" as well as "contour and define." It's described as a multitasking brush that can be used for blending, crease work, and laying down color.
It's absolutely a workhorse of a brush--it can pack on eyeshadow, blend it out on the lid or in the crease, deposit and blend out transition shades as well as brow bone shades. That being said, for how I tend to apply products, which often means applying four to eight eyeshadows per eye, it's too large to achieve the level of precision I need for that. If you're someone who often applies one or two shades on the lid or likes a more diffused crease color, it works well for looks like that (as a multi-purpose brush).
I tend to reach for this to apply product to my brow bone, inner tearduct, and for gentle blending of edges at the end. The denseness and larger, more rounded edge helps it gently diffuse edges well, especially for stiffer powders and more matte finishes.
I loved the shape and feel enough that I bought a second one, but I was really happy when the brand released the Worker Three, which is a smaller version of the Worker One/Worker Two (but it is undyed hair like Worker Two) along with the Worker Pro, which is smaller (but a little fluffier--doesn't have quite the denseness of the Worker One, Two, and Three). I end up using the Worker Three and Worker Pro for more lid/crease work but Worker One/Worker Two for highlighting my brow bone, blending crease and transition shades (but less for initial laydown of color), and highlighting my inner tearduct.
Per the brand, the handle has a total length of 160mm with a brush head length of 15mm and width of 10mm. As part of the core range, the handles are wider than average (the PRO range has thinner, more tapered handles). You can safely assume that the brush has held up beautifully over many washings and uses; if there are any issues from washing, shape changes, and the like, they’ll be called out specifically.
Worker One is beauty blogger and makeup brush expert Sonia G.’s perfect eye shadow blender—it softens and diffuses pigment without over-blending, thanks to a combination of perfect grip and control. The versatile shape also doubles as a crease and shading brush. “I know how hard it is to find the perfect blending brush. I designed this brush to my exact specifications—it has perfect grip and control, so it never over-blends.” — Sonia G.
