One Eye Of God is a peek envelope like no other. It is an entirely self-contained, normal, and attractive gift card-style envelope. It can be shown completely opaque on both sides, yet you are able to always see clearly through it whenever you wish. In this manner, the envelope is able to reveal the secrets of its contents to you.
There are no slits or moving parts. No use of alcohol to make the envelope transparent or any chemicals which need to be applied. In fact, nothing is added or taken away. There are no moving parts. The ingenious envelope does everything for you. It is self-working and resets on its own.
No magnets. No thread. No elastics. No electronics. No holding it up to the light or placing it inside another envelope.
