Yogurt Guard / Public

Yogurt Guard

Some yogurt will stick on the cover in transportation. With time
goes by,lactic acid bacteria keeps fermenting and results in
the thick yogurt on the cover. Neither threwing the cover with
the yogurt nor licking the yogurt is good. So we add a oblagum
between the yogurt and the cover. In other words, this oblagum
is another cover behind the prime cover. When we eat yogurt we
can just throw the prime cover and eat yogurt and the oblagum.
