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. The light and bouncy Blurring Blender was created with cloud coverage memory foam to absorb less makeup and reduce waste. It also features 2 sides for custom coverage. Use the long edge of the Blurring Blender for controlled coverage and the short edge for precise application and concealing. Superior performance made sustainable. 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.
