When Non grips Superman in a bear hug in midair, Ursa soars to get something to hit Superman with. She flies up to a ledge where she snaps off a flag pole with glee as she preceeds to hit Superman, he ducks and Non gets hit instead.

Notice the base of the flag pole where it is supposed to be snapped off with Ursa's superhuman strength. It is very jagged and clearly shows it is made up of wood, spray painted silver to imitate a metal flag pole.

When a metal pole is snapped off, it is more uniform and with smaller jaggedness whereas if you snap a wooden pole you get these large splinters and fractures as well as multiple sized jagged points. Ursa's pole shows that it is clearly wood and not metal.
