This necklace is a miniature book made from solid golden brass. Inside is a secret hidden message, specially folded and fitted inside the locket to look just like the pages of a real book! The locket is a delicate size, measuring just 16mm x 10mm (about the size of your fingertip!). The necklace chain is available in a variety of lengths. Please refer to my illustration (in the final picture) for a better idea of what each chain length would look like when worn. Your Personal Message Inside The message inside can say anything you like, up to a maximum of approx 20 words.
