Bought these just outside Disneyland California in a collectables store. Can’t think of the price off the top of my head probably about $3-5 USD each. Bought 5 packets but didn’t open any. As they say they contain 3 Rub-Off Cards, 3 Stickers and 1 Stick of Bubble Gum. As I haven’t opened mine I haven’t seen what they look like inside, but some quick googling gave me this: https://www.atari2600.com/cat–Video-Game-Memorabilia–SUB120.html so those look pretty cool, it a random scratchie version of the arcade game, guessing you have to take the right path without hitting an obstacle.
I have feeling the gum inside them would be pretty horrible by now I’m not sure what it was meant to be shaped like but it seems to be all broken up inside the packets. I don’t think they were like that when I got them but it doesn’t really matter.
