In the video, They talk about Passion for Lamy.. To build the brand around Passion.. and to Instill in its patrons pride..
That is the basis of marketing jewelery. Or a roundabout way of saying,
=== How do we make people buy something they Can't use and Don't need.. ===
Similar to how watches have survived, the goal is to attract middle class idiots slaved to a job which rob them of the time to create and foster their personal identity.
And so, they take their meager pays to BUY an identity in a product such as monteblanc or lamy or kmac..
It's the same schtick, only with extra frivolous german engineering...
It's like anything, these days. Look how many advertisements have nothing to do with the product itself.
Take this Apple HomePod ad for example:
The first half of the ad is just depressing, and when it finally gets to the product, it could be replaced with anything that plays music and not change... she could put on a gramophone for crying out loud.
As for pens, there is a certain kind of appeal people are drawn in to. For me, fountain pens are aesthetically pretty but awful to write with, especially for daily use. I have gel pens that write far better and without any fuss or consideration for paper type, etc.
I use pencil mostly anyways (engineering). I've recently found 0.4mm mechanical pencils, which are pretty well perfect. I also use 0.2, 0.3, 0.5, 0.7, and 0.9, for various purposes.
I might do an overview of all the writing instruments I have. I've developed quite the collection, though as with keyboards, there are some you just gravitate to.
