The Blue Workhorse is a great all-purpose pop-up sponge made of an open cell material that is very absorbent. Mudtools has shaped it like a potters 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 unpredictable and we try to be environmental conscious about what materials we use and the long term effects. Mudsponges are made of a biodegradable and environmentally friendly material that is incredibly durable.
