I think the price is definitely justified. These are metal and I can't find them anywhere else. I know of some keycaps can cost upwards of hundreds of dollars because they are so rare and hand carved. Only a few get made every few years.
FolioLOlz i can find the maker of theses on geekhack. I can also buy them second hand off someone for a bit cheaper. So i don't know what the hell you are talking about.
