Decent brush. Applies well. But after only using it for a bit, the end with the bristles fell off. Packaging is horrible.
"Brush ideal for contouring and blending in the crease and corners."
This brush is quite small and the bristles are only about 5mm long. It tapers into a rounded end. Because the bristles are short, the brush is quite firm. I've not been able to get it to work in my eye crease, however, i've found it quite good for smudging eyeliner and applying shadow on my bottom lid.
I have big eyes and a deep eye crease, so this might work on someone with a different eyes to me.
