But it doesn't make any _money_. Approximately all the ballpoint pens in the world are dependent on a single company, Mikron Group. It has a market capitalisation of about CHF 275.5 million. "We're the only ones who do that" is insufficient; it has to make money. And honestly, generally, "we're the only ones who do that" is a strong sign that a thing doesn't really make much money; if it did, well, other people would do it.
