there is a production date on the box, and there is a limited use date under the bottle. If you buy it in a store, it is generally not fake. It is best not to buy it online, because Marubi is only available to franchisees who install cabinets, and it is not sold online. Moreover, there are three positions on the red packaging box to distinguish the true from the false, a circular trademark, a bar code at the bottom of the box, and an exclusive franchise number belonging to the franchisee at the seal. Generally, with these three, it won't be fake. The point is still to see where you bought it. It's very important.

Oh, by the way, you can smell it, too. The taste of Marubi series is very special, with a fragrant smell. It is a unique flavor designed exclusively by Japanese Spice Teachers College for Marubi High Energy, with a faint fragrance of rice in the field.
