Paradox Button by Julio Montoro & Ultrabello

A button with two holes is placed inside a sealed envelope.
A red thread passes cleanly through them.
Everything makes sense.

Until you remove the button.

You peel off the holes.
They were never holes at all.
Just black stickers hiding the truth.

And what looked like a button from the very beginning was never a button.

Welcome to Paradox Button

A visual paradox revealed only at the end.

Nothing breaks. Everything breaks.
