Japanese carbonated orignal flavour Ramune soft drink. Ramune is a well-known drink to Japanese people. Ramune is a phonetic distortion of the English “Lemonade”. The bottle top is sealed with a marble which can displaced into the bottle (by pressing firmly) which allows the release of ramune for drinking. This is extremely fun for kids. A similar lid design was previously used in the U.K, but it is not currently manufactured.
