I purchased this shoe shine sponge from a local department store.  I was in a show with no time to do a proper shoe shine and needed a quick shine for my shoes. It worked great. After using it, my shoes looked like they had just been shined professionally.  The only drawback is that the shine doesn't last very long; I only wore the shows during the performances and I had to use the shoe shine sponge every evening because the shine from the day before had completely lost its luster by the next day.  Great if you need a quick, though temporary shine for your black shoes.
