What's the thinnest E-ink screen that is closest to 3.5×2.5 inch? (sh.itjust.works)

I am curious if one, something like this exists, and two what the cost might be? I am looking for a screen, I assume an e-ink is the best/cheapest option and I want it to be as close as possible to the size of a playing card, ideally not thicker than 2MM. But I think up to 5mm could work.

Basically the idea is to use and or eventually create very thin cheap e-reader screens to make programmable playing card games. I have no idea if the screens are even that small, when I go to look for them I get results that are very far from what I am looking for.

Anyone know if what I want exists, and if not, if it would even be possible to manufacture for cheap?

Edit: I wonder how hard it would be to repurpose something like this?

The idea is that all the "cards" would be inserted into a carring case that acts as a dock to update the cards. Once you pick your game, all of the cards refresh to whatever game you picked. I would want to make the games open so anyone can design a game for people to play.

Even if you find screens that thin, all the electronics you're going to need to make them usable will add considerable thickness.

But once the display is updated, the circuitry isn't really necessary. Maybe you could reduce the thickness and the duplication of circuitry by having a "dock" with the circuitry where you insert the card to update it.

That's exactly the idea! They would have pins somewhere on the buttom, you would plug all your "cards" into a dock that would act as a carrying case. There would be an open source website where people can design different games and then you choose one of the games and it refreshes all the cards to whatever game you want to play.

That's the idea anyway, whether it's feasible for something people are willing to pay is a different question.
