Rihanna's Fenty Beauty recently released a dry-brush-cleaning sponge, which Fenty Beauty says quickly removes pigment from makeup brushes and allows users to easily switch from color to color while using the same brush. Insider producer Kyle Kerchaert put Rihanna's latest tool to the test by creating a multicolored eye-makeup look using just three brushes and the sponge in between. She rated the sponge on effectiveness, speed, and versatility.
