These cute little mermaids are perfect for your beach read or just to let your love of the magical shine. The Mermaid sits inside the book with the tail hanging over the binding, and the bead (sea bubbles) and charm dangle down the spine of the book. They are thin, so they won’t cause damage to expensive books, and no more dog earring pages. Sorry by but I have not figured out how to use them with Ereaders... Each Mermaid is 8 cm (3.14 inches) long. All the beads used are glass. And there is a different Sea Life charm on each. Available are: Mermaid with Fish, Mermaid with Clamshell, Mermaid with Anchor, Mermaid with Starfish, Mermaid wth Crab and Mermaid with Sea Turtle. The phots are the best way to see the colors of the glass beads, as each is a bit different.
