Throw away and refillable without replacement support is a huge business which seams to have been around for quite a long time.
Back in high school our student desks still had inkwells. Very few of us kids actually used them though.as most used ballpoint.
However in one of my English lit. classes the Teacher demanded that all work be turned in only done so by quill. His theory was that society as a whole was on such a downward spiral that one day even cars and all home appliances possibly even the telephone would be manufactured as throwaway items,but he nor his students if he had anything to do with the prevention of societal decay would not be contributors. In some small way at least part of his teachings and almost daily rantings may have helped me through the years.
