Drinks

There have been two lines of themed Drinks for the Hetalia series so far.

Canned Juice
A line of Canned Juice (缶ジュース, can juice) was released by Mars Sixteen in October 2009.

There were 6 flavours, available on Animate for 150円 ($2) each.

Due to being disposable, the cans themselves have become incredibly rare. They aren't resold often enough to show an average second-hand price. Each can has a picture of a character on front, with their flag as the background. There was a different flavour for each character, as follows:
 * Italy : Grape
 * Germany : Coffee
 * Japan : Green Tea
 * England : Tea
 * America : Orange
 * France : Pear

Bottled Tea
Two more drinks were released on November 10th, 2009.

They were sold on Animate for 200円 ($2.67) each.

As of yet, they don't seem to show up second-hand, so no average price can be obtained.

Each bottle has a chibi picture of their character, as well as a different titled flavour, reflecting the character used.
 * Japan's flavour is "Excuse me, it is Green Tea" (「恐れ入ります、緑茶です. 」Osoreirimasu, ryokucha desu )
 * England's flavour is "English Gentleman's Tea - Straight Tea" (「英国紳士紅茶 ストレートティー」Eikoku shinshi koucha straight tea )
