What do you think of Red Bull's championship ring?

There is a winning word on the tab. As long as you confirm that you have bought a promotional drink, there will be detailed instructions on the cans. Red Bull's prize is set under the metal pull ring, so the human eye can't see through the metal, so there is no winning prompt on the outer packaging, so it is impossible to see whether Red Bull has a prize, so you can only buy it yourself and open it to see if it wins.
