Element Brooklyn - Plant-Based Kitchen SpongesA biodegradable sponge effective for all uses in the kitchen and around the house. We tested over 50 different natural materials and found this product to be the most similar to typical kitchen sponges. One side is made from coconut fiber, perfect for scrubbing and cleaning. The other side is highly absorbent cellulose. Theyre durable (you can even put them in the dishwasher!) and compostable and the packaging is 100% free of plastic.
