That's not a deck. It's a stack of thin, deep-red transparent plastic slabs in the same approximate dimensions as a poker-sized deck. But I'm sure you knew that already!
I've found totally clear decks - I think the Blue Crown is selling one as a gimmick for a magic trick by Joshua Jay. I've even found plastic slabs that are thick, the same thickness as a pack of cards, and cut around the side edges to look more like a pack of cards from a side angle. But nothing like that. You'd probably have to make it - it's not that hard and would only need some simple tools.
Watching that, the novelty factor wore off quickly - you can't tell if the "cards" are being handled face up or face down and they all blend into one images of dark red, whereas a pack of cards is more distinctive from card to card and you know when it's face up. But that's one man's opinion.
