Don't do it.
I bought this for my 4 year old boy who loves Moana and Maui. He had it for literally 24 hours and the stone unhooked from the loop holding it to the necklace. I used a pliers to put it back together. The stone is plastic, and not as vibrant of a green as I expected, it is more of a jade than the actual heart of te fiti. For 27$ and 9$ shipping and handling I would not purchase this item again. I would not recommend it to others.  There is a plastic one on here somewhere that seems a much more practical toy and has a necklace that opens and closes to put the green heart in.
