In those days, it was rare to keep in contact by anything aside from a letter. If you're storing the things for safe keeping and the following owner places it away for safety - when does anybody get to utilise and like it? I ultimately decided it was better to have something in use rather than just passing from one generation to the subsequent without being used and eventually discarded and never used.
It also teaches your folks a little bit of history about the things as you see and debate them. As an example : Try a product which has invested in clinical results to guarantee your eye safety.
