1. Small magnets are implanted in these two necklaces, and when you pull them close enough, a mild suction pushes them together. They're like a physical manifestation of you and the person you care about, and you'll always find your way back to each other. 2. The two necklaces are designed like the sun and the moon, and they represent your wish to remind him/her that no matter what happens, you will always be there. They hold a special meaning that "I Love you to the moon and back." 3. The necklace conceals a projection stone that allows you to see the hidden information when it is near the camera or your eyes. It's like a secret waiting to be discovered. If you want to project the words, please hold the projection stone close to your phone's flashlight at night.
