I've done a few bits and pieces of calligraphy, but actually for this one I'm just using some disposable technical pens as I started it whilst away from my usual workspace so didn't have access to them. As for the paper, it's actually a smooth watercolour paper (super thick at 300g/m^2), so it gives me the option to paint it afterwards if I want, but otherwise is just a very nice surface to work on.

*Edit* - Also I was planning to do it on A3, but as I said was away from my usual space (not that I have any A3 watercolour) so did it on A4 instead.
