They are made overseas and imported by Parker.

From what I've heard from someone whom I trust re: arrow shafting, weight tolerances are fairly poor even on the premium shafts (which would lead me to believe there is a wall thickness issue), and they have some other minor QC issues (however they purportedly are pretty good for straightness).

If anyone wants to send me a dozen to test (not shoot, just test) I'd be glad to, but I'm leery of putting out the bucks for them myself. Of course I would send them back.
