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.

I think your best bet is to look for an appropriately sized electronic shelf labels, there are companies that specialise in them and they are already quite thin, battery powered and have bluetooth or nfc connectivity to change images.
