Very interesting! I tried serching them up but there’s not a lot of information for that particular brand. From what I gather they are nibs for dip calligraphy pens. You may be able to find a nib holder and a bottle of ink to use them. If I recall, you go through calligraphy nibs over time due to the harsher chemicals in the ink corroding the steel, typically with India ink. But you can use regular fountain pen ink instead. Just don’t put India ink in a fountain pen!
