I bought it to use as a stopper for a soju bottle, but the size is large and I think it will only fit a wine bottle

It's just for closing... I bought it for vacuum storage, but the vacuum doesn't work. There is no feeling of being pressed, and as in other reviews, it is difficult to turn it by locking it into the bottle. Even as an adult male. It's good to just use it instead of a cork or to close cheap things like house wine.
