When I had ordered this last year I'd received the original Dr. Hagiwara Green Magma made in Japan; the one in a glass jar. When it recently came time to re-order, I just went to my trusty Amazon account, found the old order, and re-ordered the same thing. However, what I received this time is the green magma that's made in the US and comes in a plastic container.The original from Japan is much better; it dissolves better in water and is a darker green. Plus, the glass container seems to keep the green magma fresher.I'm sure the American version works the same way as the Japanese version, but beware if you're expecting the real stuff from Japan -- this isn't it.
