How does projection jewelry work? 🧐
This photo projection keychain has three methods you can use to see that secret image inside.
✅ Method One: Turn on your phone camera and touch the projection stone to your camera lens. The image inside will appear on your phone screen.
✅ Method Two: Hold your projection stone from the back and turn it upside down, then touch it with your phone flashlight or any other light source. You'll see the image on the wall in front of you, if you are in the dark.
✅ Method Three: Simply look into the stone with your naked eye, as if you were looking into a keyhole.
