This is a very rare game case. Not many like this around anymore. Its a normal Eraplast game case with "Permastruct" instructions for the game Tetris inside. The instructions are printed on a sticker that fits the game case and are readable inside of the case. Very unique idea so that game rental stores wouldnt have to fear about instructions getting lost or stolen when the game was rented.
It even talks about how you can play a co-op 2 player game and then remarks how the game is from Russia and how it sounds like Communism.
