Plastno's biodegradable cellulose sponge is a plant-based, plastic-free pop-up, sold in a 3-pack. Each sponge ships flat and compact, then expands the moment it hits water. Soft, ultra-absorbent, and free of the microplastics that conventional foam sponges shed in every wash.
The Soak Sponge replaces polyurethane and polyester foam sponge
