Hex Materials

I had an idea to use the like Catan Hex pieces to build out the hex crawl map in a fog of war kind of way
But i was gonna tape or stick paper to the hexes so they looked more on theme
however i realized I don’t have the Catan game anymore as i gave it away.

How/where could i acquire similar quality (or at least like, weight / size) blank hexes that i can draw on or stick stuff on? I don’t wanna use paper cutouts cuz they move around and are annoying to deal with, which is why i ask.
