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.

Try finding it on AliExpress. Just search "e ink display" or "e ink screen. The webiste is hot garbage but their app is ok.

Thanks I did try before, but now I had success. I stumbled upon those little price tags stores use to digitally update prices. Those could possibly work for this.
