Drawing with a pen nib that needs to be replaced is terrible! It makes that scraping noise! I don't have any more pen nibs, but I needed to draw! I'm going to wait until I get more to color the drawing in. It's Lyra's head.
The nibs were supposed to last a year. I got my first set on Christmas of last year. (along with the drawing tablet) but now I'm on my third set. The sets come in fives.
