Train-themed Japanese green tea
For just over a year now Mokku Company, purveyors of novelty drinks, assorted confectionary and miscellaneous goods, have also offered a brand of green tea contained within a E231-style container. In addition to this Yamanote Line version, Mokku also offer a Keihin-Tohoku line train, too.
As you can see below the design is authentic enough with the large top removing to reveal a pretty ordinary pet bottle beneath. I like.
