This brush is extremely soft and does not irritate my sensitive eyelids. Very soft brushes like squirrel brushes usually do not grab a lot of product and you can only work in very light layers. (I prefer squirrel for face powder, light layers is what you want here!) The fox one is different. It provides the softness of a squirrel brush and at the same time the grabbing power and workforce of a goat brush. The bristles seem really sturdy and not as delicate and fragile as squirrel hair. I have not had any fallout either. The hair is really amazing. 10/10 - I really recommend this brush.
