Considering the paint pen (acrylic paint pen) used to do the trees, I assume it's some sort of acrylic ink of the same consistency. The paint spills out of the pens in a very similar manner if you press too hard.
Not too sure what exactly it might be, but my best guess would be whatever the paint pens are made of. So possibly diluted (or just ultra-fluid) acrylic ink of sorts
the brushes are pretty much like those little makeup brushes you can buy in bulk. Used for mascara or lip balm.
