I recently purchased a Sasieni with a florid fish looking stamping and a patent number. I don't have the pipe yet and the patent number was not shown in the photographs. But I believe it has it. "The pipe has four blue dots on the left side of the stem, and four blue dots on the right side of the stem." My simple question is, "Is this a four-dot or an eight-dot? This sounds like a ridiculously simple question. And is if you know the answer. However, one person sees four-dots shown on each side of the stem, someone else sees a total of eight-dots. Which is it?
