This is a PIPE. There are no provided instrictions on how to install the brushes and the GIMP documentatio was also not super clear. I thought I was getting an easy to instal set of brushes. The prince is great, but it was more work than I wanted to figure out.

I didn't realize that this was a pipe. Once I figured that out though I was able to peel everything apart to use specific ones as individual brushes for detailed work. used this to make that nice and quick. http://registry.gimp.org/node/28268

I did rate the other one 4 stars though because of the above issues.
