I got these fabulous "evil eye" beads from a friend of mine in Israel. These fun charms make a great bas mitzvah gift. I gave a similar necklace to a friend's daughter, and now all of her friends want one too! I just tell them to wait their turn. ;-) All of the metal components are nickel and lead free, certified to current safety standards. The chain is 18 inches long with a 2 inch drop.
All evil eye beads have at least two sides. One looks out to protect you, but the other one is watching what YOU do, too. This is to remind you to look at everyone with your "good eye", and not to use your evil eye, because it goes both ways!
