The corner of all pieces was fully pressed and folded together- some thing I assume it was from the manufacturer, but not even from the courier- as the type of impact could have been from powerful item like forklift..etc.. But inside the cover they should have included: WARNING- VERY SHARP ALL OVER, AND WHICH SIDE SHOULD BE ON TOP.

These were brilliant mounted on OSB board made a great log shed and mower stall

Great product used on shed roof will last a lot longer than felt. Easy to use

Fabulous coverage and looks great.

Excellent product
