Love, joy, and learning...does it get any better than that? This beautiful neurotransmitter necklace includes dopamine, serotonin, and acetylcholine. It's the perfect scientific symbol of a balanced, happy life.

The pendants are made from lead-free, nickel-free zinc alloy, separated by non-tarnishing steel beads. They are hand-strung on an 18 inch non-tarnishing steel snake chain.
