Thanks! That means this pipe is most definitely older than I am, as I was born in '80. That seems to line up with my online research, but you're correct, nobody has much to say about the two dots, other than that they're generally nicer than most of Sasieni's off-brands, but not quite on a four dot level. Can't find many out there either.'46 to '79, but little is written about Two Dots. I assume they follow the same era's as Four Dots.
