Used and Unused / Cup

Used and Unused

In many occasions after we use the disposable cups, we always mix them with unused ones. Disposable cups do bring many convenience to our life. However if we can’t distinguish those used ones from unused, there’s no convenience then. So how can we differentiate them?
