The Nyx Blending Brush #16 is a fluffy domed brush made with synthetic bristles. Nyx isn’t exactly known for their makeup brushes, but I wanted to pick one up since I got to see them in person at the Mall of America Nyx store. This brush is super soft, softer than both my Sigma and Zoeva brushes, so it feels really nice on the eye area. I like to use this brush for both applying shadow into the crease and for blending out shadows. It is similar in size to the Sigma E40, and works to blend out shadows in pretty much the same manner. This brush is just a bit more dense than the E40. As far as applying shadow in the crease, I much prefer using the Nyx #16 over the Sigma E40. I have gotten so much use out of this brush, and it remains as one of my go-to eye brushes. After my experience with this brush, I will probably purchase some more Nyx brushes in the future!
