This is unused but the outer box is poor - the contents look very good, however. See photos. This has some sort of powder in it you mix with water but it would be VERY old - 1960s to 1970s ?? Still usable? I don't know. Made in Western-Germany - found at a local Utah estate sale. I can't find anything like it that has been offered for sale. Ships out to you from Utah. I ship daily!
