give or take, something like a flatbar will probably only be around 3, while something like the whale tail box i think was around ten since there's so much coping, all the laminate has to be warped the right way, and the whole box has to be welded from metal scaffolding. All of these are handmade too, keep in mind its not like a car production plant where everything is automated, every piece is done by hand
and frankly who cares what it cost? it didn't come out of my pocket, and those rails are awesome
