The Blue Workhorse is a great all-purpose pop-up sponge made of a very absorbent open-cell material.. We’ve shaped it like a potter's rib to fit comfortably in the palm of your hand. Dyed with a natural pigment, the color will fade with use.
Natural sponges have been used by potters for years. However, the quality of natural sponges can be inconsistent. Because we aim to be conscious about the long term effects of the materials we use on our planet, MudSponges are made of a biodegradable, environmentally friendly material that is incredibly durable.
Each MudSponge is shipped compressed for economy of space-and for the fun of watching them expand when first dipped in water.
