Sangaria Ramune Grape
Grape flavor. Ramune Soda is a traditional carbonated soda that is known for its glass bottle and glass ball marble stopper. The original ramune was lemon-lime flavored, and "ramune" is actually an old Japanese word for "lemonade."
To open: Pop out the plastic plunger from the top and push down on top of the cap until the marble pops down into the special chamber along the bottleneck.
