Sonia G Worker Three is a brush that retails for $32.00.
Sonia G Worker Three Brush ($32.00) is designed to "pack, transition, and blend" eye products and is a "smaller version of the Worker Two." It looks a bit like your typical eyeshadow shader brush for packing on product, but it has a much fuller body, which gives it a denser and firmer feel. The rounded, more dome-shaped edge is reminiscent of blending cult-favorites like MAC's 217 but denser, firmer, and more efficient at diffusing and softening edges. It's made out of Saikoho goat hair, which gave it a smooth, silky feel against my skin, and it felt soft in every direction.
The smaller shape makes it more functional for me and makes it a true, multi-tasking brush--it is fantastic at applying color to the inner corner, lid, or into the crease, and it makes quick work of placing and blending simultaneously. That fuller, more rounded shape is what makes me prefer it for applying color to the inner corner/tearduct area and diffusing upward toward my inner crease/brow bone as well as applying stronger color (especially chunkier shimmers) underneath my brow bone. I am greedy, though, because I'd like an even smaller one...
I'll like buy one or two more of these in the next restock. As someone with a robust collection of equally-soft, equally-luxurious, and equally-functional brushes, I've been incredibly impressed by how many Sonia G brushes have become go-tos.
Worker Three is a smaller version of the Worker Two. It has the same shape and functionality but for smaller eyes or for those of desire more precision.
