The Sigma logo is fading but the brush has not shed on me once at all.
PROS: affordable (i think so compared to MAC)
VERY good quality, doesn't feel cheap at all
Dense, making your foundation a more full coverage and it doesn't soak up the product
soft - i love how it feels, i love synthetic in general
the angle on the brush makes it perfect for getting into the sides of your nose and under the eyes
CONS: i don't have more! i want to order more in the future
