Edible chocolate deco

Really admire Japanese and their ability to create such cuteness. Saw these on Meiji website. 

So cute and they are made of chocolate and are edible. It is quite creative of the Japanese. It is just like an edible greeting card for you to put whatever message you like. 

I have a hard time trying to read the instruction on the Meiji website on how to make the "glue" to be use to "stick" the wordings and deco onto the chocolate bar despite spending few months learning Japanese Language.  How I wish they have a English site.
