.. kids today pfft
but I just read this
"Beverages began using this new type of tab in the United States by 1977. Such “retained ring-pull” cans supplanted pull-off tabs in the United Kingdom in 1989 for soft drinks."
So its likely those stay tabs were used in japan in 1984 , but why the fuck did UK wait till 1989??
Also this was a thing for a very short time in the late 70s
