To print two items you have to use two of them.
Note that most items are produced in multiples, not individually, unless you mean two
different items, in which case yes.
And we could maybe add even more lore/background for them later once they're going to remain unchanged/as is, but they were only just released a few weeks ago. So going to give it more time. But that's also optional. There are quite a lot of areas of the lore that are not fully explained and you can fill in blanks as you prefer. This is intentional, and some players are quite good at coming up with creative explanations for why things are the way they are. In fact, some of these explanations eventually become actual lore
Those are really pretty minor points in the bigger picture, though, where you have a large world in which very few of the finer elements and connections are made explicit, and you're playing only a sliver of that world, for a sliver of its lifetime.
