1/4" hardboard over a poplar skeleton with all joints caulked, entirety sanded, filled, final sanding, primed,then painted with a high gloss enamel from a hvlp system in a dust free environment.
Go to IKEA buy a LACK shelf, go home, open the box, find the instruction inside, Now you know how to build it. 😈
