Ramune is the Japanese transliteration of the English word “lemonade” or soda, and is a refreshing soda which is often drunk during festivals. This variety of Blueberry ramune has a delicious, refreshing flavour! The iconic shaped glass bottles that ramune comes in are sealed traditionally with a glass marble. There is a plastic opener provided on the top of the bottle, which is used to push the marble into the neck of the bottle and release the liquid. The marble is then trapped inside the neck so it won’t come out.
