Made from corn sugar instead of petroleum these toys disappear in about 3 years if they get lost at sea, as so many beach toys do, or if buried in soil. You can even compost them!
Contrast this with the 500 years it takes regular pale and shovel toys to disintegrate. Don't have a beach or sand box nearby? These would probably make pretty great tub or splash pad toys as well.
