See the mention of wakil cap dagang ON?

A rep from the company would be able to tell easily.

Many giveaways can present themselves in replicas, e.g. the seal not reflecting light the exact same way, the serial code is of a slightly different font size or type, the thickness or smoothness of the printed label, the exact color tone of the prints, etc.

It could. But that would also mean the FB post mentioning "tiruan" is potentially misleading.

It's KPDNKK's official FB page. (if that lends any credence, I get what you mean )

But on a neutral note, from these shots, you can't really infer anything, as a copy would look really similar.

Can only spot differences in terms of, for example, the plastic tub's supplier and marks.

If it's unofficial, well I woulndn't mind buying as a consumer, but if it's a fake, darn a**h****.
