I went to South Korea.
This picture is 76% Xylitol Gum in South Korea's supermarket.
The following photograph is the same place.
It is 100% Xylitol Gum.
In Japan,100% Xylitol is dentist academy monopoly.
There is a difference of consideration concerning teeth of Japan and South Korea.
Japan called an advanced country,
but I think that Japan is an underdeveloped country for teeth.
I am regretted.
