My eyebrows are thin, have a shape but are fine, have a few chips, and I think the bristles are normal thickness. This brush is much easier to use than thick eyebrow brushes. I've used two thick brushes from Addiction Bisyoudo, but they weren't suitable for me. A brush this thin gives me more maneuverability for creating the outline of my brows, shaping them, and blending them in places, resulting in beautiful brows. I can't do my eyebrow makeup without this brush. You can turn it into a screw brush in an instant by flipping it over, and there's no hassle in changing the grip, so to put it mildly, it's a godsend. I buy a new one about once a year, and I've bought three in total. (I bend the screw part when using it, so it sometimes breaks.)
