Switch.

"I like this as an option to mix when I'm working with my cheekbones. This really helps pull off all that product a hell of a lot better than a paper towel if you're someone who uses paper towels. You can switch between creams and powders, which is what this brush is meant for. This is really going to lock them in place. If you're someone who struggles with your makeup disappearing, it really creates that undeniable dimension when you layer light layers of creams and powders."

"Sometimes I forget to use my Sigma Switch and I like reach for a paper towel. I always have a paper towel in case I like spill stuff, but it just doesn't work. It doesn't work as well. This is so good. It's just like this rubber, if you didn't know, it's just this little rubber pad. This just pulls off all that product so you can switch between shades without changing your brush, which is the point of this."

"I'm going to dust off that same brush onto my Sigma switch which if you don't have one of these you really need one. I have it on my desk at all times it just is great for switching colors on your brushes."

"I love this thing by the way. If you're a makeup artist or if you film, you need this, the Sigma Switch. It just kind of takes off any leftover eyeshadow so you can keep using the same brush and blend or go between colors and not stress too much about it."
