Back on the marketThe New York Times and many women herald the return of the Today's Sponge. No sponge article would be complete without mention of the Seinfeld episode where Elaine buys out the Upper West Side's supply of Today's Sponges. Allendale Pharmaceuticals, the New Jersey company that markets them has a thorough site about Today's Sponge.
