The Blue Sponge is a great all-purpose sponge made of an open cell material that is very absorbent. We’ve shaped it like a potters rib to fit comfortably in the palm of your hand. Dyed with a natural pigment, the colour will fade with use. Natural sponges have been used for years. However, the quality of natural sponges can be unpredictable and there is the issue of environmental pressure on the little guys. Our sponges are made of an environmentally friendly material that is incredibly durable. Size: 2.63" tall, 3.75" wide.
