Mini Booster

Sonia G Mini Booster Brush is a small, subtly-rounded crease brush that tapered slightly along the edges. It is the smallest crease brush in the line, and it seemed narrower and less tapered compared to the Crease Pro (which is closest in size but is still bigger). Per the brand, this is a "baby version of the Blender Pro" and is designed for working in "smaller areas" or "with hooded eyes."

It is significantly denser than the majority of smaller crease brushes I've encountered, and the edge is soft, domed with a hint of definition, so it can fit well into the crease and deposit a lot of product but can also move and spread it out for a diffused result. More pointed crease brushes can sometimes deposit color too heavily wherever initially placed, so the rounder shape here is particularly useful because of the brush's density (which yields greater pick up in a single go).

The brush was soft, smooth, and comfortable to use in buffing, circular, sweeping, tapping, and patting motions--I never felt the individual bristles no matter the direction or action I took with it. The brush head retained its shape well after washing.
