Animal fiber sponge: A Greek natural sponge.

A sponge (/ˈspʌndʒ/ SPUNJ) is a cleaning aid made of soft, porous material. Typically used for cleaning impervious surfaces, sponges are especially good at absorbing water and water-based solutions.

Originally made from natural sea sponges, they are most commonly made from synthetic materials today.
