Wolfe sponges are high-density, extra stiff quality, and made from open cell foam to give a consistency similar to that of a sea sponge. They have a rough texture which is ideal for spreading makeup over skin, blending the colors, and even working special effects into the makeup. The normal size is approximately the same as the palm of your hand, and can be used to cover large areas of skin.  The sponges can also be cut in half for more precise work. The sponges feel soft on the skin and are easy to clean.
