Those pens look great! I love the bigger ones that are more for calligraphic writing. I always wanted one like that in school, but since they are more expensive I never got one and then I forgot.
I used to have a regular pen like that for years of school before I switched (more ot less voluntarily, I had a wonderful pen but it broke and then I had to get something new) to a ballpoint pen (still with ink like in the other pens though, so there was still no pressure needed to write).
