Very flimsy board.  Building the shelves were easy but the directions are horrible especially when they want you to build upright one side top and bottom and them screw in the shelves across...near impossible on ones own. Also it’s a mixture of wood pegs and metal screws. I put in a screw that broke through the shelf veneer because it went too deep but there hadn’t been any resistance. It was cheap though and will serve its functional purpose.
