Have you ever found yourself going for a picnic or some other outside event and bringing a bottle only to remember that swigging the contents by the neck might not appeal to all participants?

The glasses would need to be moulded carefully so as to nest tightly but still allow air flow inside when you want to separate them from each other and make a toast .
