~Implant grade & some degree of polishing, not raw cuts. All-n-all, quality for this price range. Though, I have to mention the threading - it's hard to work with, gritty & difficult to align/keep aligned. Seems a thing w/titanium tunnels (in this $ range anyhow). But, their quality in materials & finish, make it possible to leave them in & clean w/brush in-ear. So for me, it's worth the hassle of installation considering quality vs price. Shipping was very fast & price fair, quality vendor!~
