The Elf's Blending brush is so easy to use for anything. I personally like to use it for applying my foundation. It blends out the foundation smooth and leaves your face looking flawless. It's affordable and good quality. You can also find it in most stores.
The real techniques blush brush is easy to use and it's also affordable. This brush is easy to apply your favorite blush. It's soft and it distributes the blush. It's big enough to use so it's really easy.
The real techniques powder brush is a good quality brush to have in your brush collection. It's big enough to Powder you whole face instead of using a tiny brush. You don't have to keep dipping your brush into the powder. With the real techniques brush you only have 2 dip a couple times. It's easy to use and it's affordable.
