Here are two chewing gums. On the left is from China and the one on the right is from Japan.
Peep inside and you find something in the Japanese box.
I looks like post-its
I was wondering if it was some free gift. I was about to draw funny things on the post-its and stick them all over.
Then my Japanese friend pointed out that the post-its are provided so that we may use it to wrap the used gum before we disposing. The note on the box also mentions that the glue used to hold the individual sheets of paper together is a edible glue. Nihon jin are truly cleanliness and food safety conscious.
