This shipment was horrible. The packaging was ok but these shelves came with no instructions or screws. Looking at the backs the way to hang these shelves was by a rockler keyhole slot. ONly 2 of the 3 shelves had these screw holes and one came with nothing. Then the ones that came with the keyhole screw slots had the slots drilled crooked so it made it very very challenging to hang the shelves up. I am very disappointing in this delivery.
