I love these so much we used to sell them through our little online Apartment Therapy store years ago. They were hard to find, but leave it to Anthro to solve that problem. Designed for public schools in France, the "sweetly scented, softly foaming vegetable-based soap" rotates and slowly wears down. New soap replacements just get screwed onto the "spike." It's a great solution for kitchen sinks, bathrooms without a lot of counter space OR beside bathtubs or outdoor showers. Oh, and it's a conversation starter as well.
