I bought the pearls for our son's wedding.  I'm very happy with the weight and color.  The clasp is the old fashion style where you thread and then push or pull.  It took me awhile to figure out how it works, so be careful you don't break it in the process.  It would be nice if they included a small diagram explaining how it works.  It's just a tiny bit wavy, but when it's on the neck it's not noticeable.  For under $25.00 they are a good bargain.
