Apply and blend foundation or other liquid formulations with these EQO-friendly makeup sponges that are 44% biodegradable. Their natural, earthy appearance is the result of a blend of rice husk and corn powder. The small, rectangular shape makes it easy to apply product to those hard-to-reach areas such as underneath the eyes. These sponges are ideal for both hygienically testing makeup in a retail setting or for professional makeup artists working with many clients.
