I bought the whole kit for my son, 3 1/2 about 6 months ago. He always wants to make aliens. We ran out of the matter and meteor mud, so I was very glad to find a refill kit that was reasonably priced. It even comes with new alien molds. He can even make aliens by himself with a little supervision so that he doesn't make a mess.Get more detail about Martian Matter Alien Molder Refill 1.
