Sketching with a new pen

Testing a new pen I bought, Copic Multiliner SP, and I have to say that this is the pen. I'm not the kind of person who immediately wonders which pen or paper the artist uses when seeing a good drawing, like the tools would matter, and I haven't noticed much difference between the pens I've been using before, Pigma Micron or Staedtler or some other brand. But now I know that there is a difference between a good pen and then all the other ones. Glad I found the good one.
