Made of 100% Wood Pulp, these eco-friendly Compostable Cellulose Sponges bring vibrant colors to your kitchen or bathroom. They are designed to be reused for up to 6 months before disposing, and will naturally biodegrade and compost. An added benefit: plastic dish sponges have a short lifespan and release microplastics into our waters when used, while these sponges don't pollute our planet.
