The EcoTools Blend + Blur Duo is your 2-step process to a filtered finish. First use the brush to build coverage, then use the makeup sponge to blend. The duo includes our Full Complexion Makeup Brush and our Blurring Blender for a flawless complexion. Both the foundation brush and makeup blending sponge work best with liquid, cream, and stick formulations. As with all our EcoTools products, the Blend + Blur Duo is 100% cruelty-free, latex-free, and vegan. The beauty sponge and makeup brush are easy to clean with our EcoTools Brush + Sponge Shampoo for improved brush and sponge performance.
