I need this for when I'm able to write again.

as nice as this is, it also looks uncomfortable to hold

I need this. Buy now?

WHERE DO I GET THIS

That looks expensive to refill.

It's called the "Amethyst Fountain Pen" and I think it's made by St Dupont, although I think I found the person making it: https://www.instagram.com/p/BCwLSMZPkij/
You have to email them to find out the price, so I'm guessing it's very expensive.

Prophet Velen anyone?
