Those ball valves are not stainless, but plated brass.I bought the exact same valves. There is a thread on here that discusses these ball valves.I took a file to the body, and the ball of the valve to find out for myself.Sure enough...brass.
If you don't mind them being brass, but prefer the look of stainless then who cares.The description is misleading though.I wonder if the guy selling them knows?

If they are the same ones I got last year (they look like it) then yeah they are not stainless under the plating (one of mine broke open when it froze) and also worth noting is that they are not NPT thread but straight, which means you screw them alll the way to the end of the thread.

This guy said they are stainless so I asked him to look for a marking, 316/304, and to look inside at the threads to see what color it is. He says they ar NPT threads as well.
