Is age a thing with pencils? They don't seem to be going out of fashion and you can't really break the lead on a normal pencil, well not as easily as you could on a mechanical pencil - and it doesn't smudge as it is dry. - you can even get a solid stick of 2B graphite if you want. Regardless - I'm only really on about how long it may last. Graphite = pretty much forever. The rest? Well, if they're so good why not use whatever they use for limited edition prints etc and forget all this preservation framing nonsense.
Kids aren't being taught writing skills and haven't been for quite a while. Keyboarding, yes, calligraphy, no. Maybe it's different in Wales. I hope so.
I totally agree about the longevity of carbon graphite, but the truth be told, most people only write with ballpoint (OK, Gel, etc...) if at all. Unused, skills with script fade fairly quickly.
I could, given time to practice, write quite nicely with any instrument, but that was part of my training, and degree in college. Not so sure about the current crop of graduates.
