Ramune Lychee Soda is a sweet citrus flavored, carbonated Japanese soda that tastes like lychee. What distinguishes Ramune soda from the rest is its unique design. Each glass bottle features a codd neck shape, named after the inventor Hiram Codd, and comes equipped with a marble ball at the top. The main purpose of the marble is to seal the bottle, holding in the carbonation, but it is also an exciting way to commence your drinking experience. Once the seal is unwrapped, the marble is pressed into the bottle.
