This beautiful book locket can hold any picture or a keepsake of a loved one. It was inspired of the character Zelina from Once Upon a Time, thus the green gem in the middle. You might also recognize it from something similar from The Never Ending Story series. Perfect necklace for a gift, great piece for any cosplay, costume, or renaissance play. Perfect for any crystal lover as well. Necklace length is approximately 14 -16 inches with extender. Hypo allergenic. Made for those with metal allergies. Safe for giving when you don't really know if they have a metal allergy. I make custom orders. If you want to order in bulk please contact me, so I can arrange the order. If you have any questions feel free to ask. Thanks for looking!
