Review: Cute starter necklace! - My granddaughter showed her interest in "mood" jewelry so I bought her necklace to wear along with her 1st jewelry box. The charm works well and quickly changed color to fit her mood. The necklace chain is okay but I'm probably going to buy her a stronger one. Otherwise she enjoys it
Review: very beautiful!! love itttt!!! - i absolutely love this!! it’s more like children’s jewelry, so don’t expect it to be like high-value materials. the clasp is a little small for my hands, but it’s made for children, so i’m not too worried about it. i could always switch clasps later. the little loop that holds the locket to the chain on mine broke, but i can always fix that, so no biggie! i love that through out the day, i can look at it and it might be a different color! i absolutely love the idea of thisss!! i had printed out pics of my best buddies and put them in the locket! looks nice! (although the ink when printed is a little off on coloring - but i can always change the photos later)
