I know the price should have slapped me in the face and told me "NO" as a moderately seasoned self-body modifier, but I tried.  I haven't got any way to test if it's "really" 316L, but it does appear to be true steel and not an aluminum or lightweight compound.  However, it's not a high quality 316L.  There are visible imperfections in the steel - in both the tapers and the tunnels.  Even after thorough sanitation (not just an alcohol swap or some jewelry cleaner), using the tapers & tunnels did result in serious irritation.  My stretched lobes had to be abandoned for proper healing and I lost nearly a year's worth of enlarging.  I chose to dispose of the set after the experience rather than risk another irritation by using them again.
