Doesn't work for the Russian tiles.
Not only is the back different, they have rounded edges, so even in a bag you can feel the difference. I think they would work best with the Russian boxes, that could work.
I actually have the first set as fan printed tiles as well. This way I can use them in a game, but they don't stand out when pulling them from a bag. The actual tiles are sleeved and stay protected, although maybe I'll do a Russian game one day, and then I'll make sure to include them
