“Ramune” is a carbonated soft drink that has been very popular for many decades in Japan. It is well known for its unique bottle (invented in England in 1872) that seals itself using pressure from the carbon dioxide in the drink. A glass marble is placed inside the bottle, so when the bottle is sealed, the marble is on the top, and you can open the bottle by pressing the marble down. As you can see, the appearance of the bottle is beautiful and cool-looking especially for summer.
