I bought these to give out as class favors for my son's 3rd birthday.  I was really impressed by how sturdy they are and the kids really enjoyed the various bright colors.  The lens is actually proper plastic and I wouldn't consider these to be novelty, which makes the price point a great deal.  They are pretty dark, which is something to be aware of.  Seeing as my kids tend to damage or lose their sunglasses all the time, I would rebuy to have a stash on hand!
