Purchased one of these at a sushi chain on weekend

Luckily I didn't just hand it straight to my 4 year old to drink. Turns out the blue cap comes off and allows the glass sealing marble to roll right out into the drinkers mouth.
Am I just being paranoid, or does this product seem like a potential choking hazard and perhaps shouldnt be sold in NZ ??
Any warnings on the bottle were in Japanese.
I have never heard of these "marble sodas" until I researched it, apparently its an old bottling technique now superseded by good old caps and aluminium twist tops.
