The dolphin symbolizes playfulness, intelligence and freedom. A beautiful frosted glass magnet with a dolphin on it could represent those traits, or it could remind you of a nice place where you've seen dolphins. Maybe it could serve as incentive to go there again! The stone itself is 1.25 inches in diameter. The magnet is a half an inch. The colors are light and dark blue, teal and green. There is a minimum order quantity of 6 magnets.
