There are billions of toothbrushes abandoned every year. In our daily life, we keep a toothbrush in service for just a few months, but the service time of a toothbrush is actually longer than it is.The head of this toothbrush can be removed to a shoe brush. In this way, resources of manufacturing toothbrushes can be reduced and heads of toothbrushes can be reused and its detachability makes it easier to recycle different materials.
