Color Switch is the makeup artist’s best friend. I can’t believe how this little accessory has helped me with my work! It’s a tin with two compartments. The large black section is to wipe your makeup brush to get rid of all the color pigments so you can use another color without the muddying and I don’t have to wait for the brush to dry like when I use a brush cleanser, which really saves time. A few swipes across the sponge and I’m ready for the next color. The white little sponge in the center is for wet application. Wet the sponge and dip your brush in then your powder pigments or shadows to intensify without the mess. Love it!
