Dispongeables® are Earth's first disposable expanding kitchen sponges. They are as tough as normal sponges, but are made of 100% biodegradable and compostable plant material. Dispongeables® keep bacteria from growing on your kitchen sponge or dishcloth! Replace Dispongeables each week, guilt-free, before bacteria grows. They store easily because each patent-pending Dispongeable® begins 1mm thick and swells to a "just right" thickness when it touches liquid. Dispongeables are great for people who love sponges, but better for people who hate them! Germ free. Guilt free.
