The Sigma E40 is one of my favorite eyeshadow brushes for blending and softening harsh lines. The soft, fluffy bristles hold pigment well and distribute it evenly across the crease. It’s dense enough to pack on color but still allows for seamless blending, which is essential for gradient eye looks. I use it frequently on clients to create smooth transitions between shades, especially when working with complex, layered eyeshadow designs. The brush maintains its shape and softness after multiple washes, making it a durable choice. My tip: use windshield wiper motions to blend, and avoid overloading the brush to prevent fallout. This brush is a must-have for flawless eyeshadow application.

I received this brush as a gift 10 years ago. I still use it on a daily basis! It blends beautifully and works with both powder and cream eyeshadows. It’s also super beginner friendly. Definitely my favorite brush in my brush collection.

I've been using this brush for years. I initially used it as my crease blending brush but now I use it to blend out eyeshadow. It's nice and fluffy and blends out eyeshadow with no harsh edges or lines.
