Oh, yes, I have some of the Staedtler fatter ones too for coloring and I looked at those when I was ordering them!

I have always enjoyed having a big zipper bag of colored pens that I carry around with me to play with, but usually for serious business and many kinds of note-taking or longhand writing I can't bother to switch pens often, so I can see how the multi-color pen would appeal. When I was a kid they never seemed to work quite right, but modern technology and gel or liquid ink could cover that.
