Bought for my granddaughter, she loves the movie MOANA. I will cherish the memory of her opening the package and the jubilant look on her face. It is very rare to see her without this necklace. Here the fairy tale ends. . .I bought this on 08/12/2017 and today is 08/25/2017 and the chain is NOT glowing anymore. It hasn't worked for about a week. So there was VERY little enjoyable playtime. You CANNOT replace the batteries in this one, although I think the item description leads you to believe that you can claim you can: Moana's iconic blue shell necklace glows a soft green light - THE NECKLACE IS GREEN OR MAY NOT glow if it closes with the push of a button - WHERE "PUSH A BUTTON" - OURS DID NOT OPEN OR CLOSE Includes 3 button batteries - GIVES BUYER THE IMPRESSION THAT 3 BUTTONS ARE SOMETHING TO REPLACE I'm glad you all love the necklace too - it is just really disappointing for breaking a little girl's heart i think for the money paid for it - it could have lasted longer or the batteries could have been replaced!
