How To Open Amiibo and Save the Box.
If you want to use your amiibo with games, but want to preserve the packaging for displays this might be a technique you want to use. The card backing has a number of layers. They can be gently peeled apart, leaving the top edge intact. The box print is adhered to the plastic (it's either glue or some kind of heat seal). Once your amiibo is out the back folds down like a flap, ready to display! With care it has worked for all I've opened so far. Good luck!
