I bought the glasses for the 30th birthday of my best friend and I'm happy with it. It is what it should be: a joke article. It is made of plastic and the rhinestones are glued to the edge. It does not feel as if they would survive the next few years, but they do not have to, too. For the fun factor is great. Only the price is determined by the delivery of the short fun too high. Since I have ordered several items at the same time, these shipping have relativized ultimately for me, but only for the spectacle alone representing nearly 10 too much.
