To properly set expectations straight away, there's no mess shown in any of these four trailers. And you can't actually buy any of these videos on Amazon any more, either. But although you'd never know it from these trailers, these are all pie videos:
If you type in "Blue Leopard Media" into the search bar at Amazon, you get this response: "Your search contains adult items which have been hidden. If you wish to see them, click here."
Sadly, the Ruby Diamond trailer not only doesn't show her getting pied, it only shows her hands for all but the last couple seconds. At least the other three videos do a much better job of showing off the actresses who star in them! But you can see plenty of pics of Ruby -- both clean and pied -- in my recent tribute thread: https://umd.net/forums/fondly-remembering-blue-leopar
Weirdly, another long-defunct pie video producer I did a tribute to yesterday, PieJinx, also sold at least one 30-minute video on Amazon, and still has a trailer up there, even though that video also hasn't been available there for many years. For more details on that, see my most recent post on this thread: https://umd.net/forums/ginger-catches-yet-another-pie
