To restore or achieve a high polish on your stems, the micro mesh pads are hard to beat.
The pit or two on your stem will sand out without much problem, so, adding glue and sanding isn't what I'd call optimum.
I like that pipe because of the stem, primarily. It looks to be one that would be easy on your teeth and comfortable to clench. I've got pipes with similar stems that I really enjoy.
