The hamsa is a Kabbalistic symbol of protection from the evil eye.
It brings positive energy, happiness, prosperity and health.
The Hamsa's (meaning "five") includes five digits and symbolizes the Creator's protective hand.
The other kabbalistic features on the keychain are the eye, fish (fertility), and grapes(wealth).
This would be a great present, a nice collectors item, or can be hanged in your car.
