The quality is typical sheer pantyhose, nothing special. I specifically got these though, becuase it said they were 'sheer to waist' (I needed to wear under a costume with a short skirt and bloomers) and there IS a subtle shade difference in the tops of these.
Otherwise, they're what you'd expect.
After I got these, I found sheer-to-waist hose in the supermarket for $2.50. Go figure.
