Then glue the mirror to the box on the edge. After that, the clerical knife we cut the box along the contour of the mirror only on three sides.
Now push the mirror inward. Open the box and fix the bent mirror with hot glue.
We perform the exact same operation on the opposite side of the box so that the second mirror is diagonally from the first.
