Dolphins may be smarter than humans but humans sure have been smart enough to know that the cute marine animals make very good everyday companions in the shape of key holders. These adorable rhinestone designs capture dolphins as they were meant to be, in the middle of a tumultuous jump from the depths of the sea. The eyes of the dolphins are well-defined thanks to the crystal settings. The pendant is hardware with a zinc alloy that makes it sturdy and durable. This is a great item to collect multiple versions of.
