(1) the recognition of the quality surface of the hollow plate. A good lightly pinched edge will not show sag, while the poor quality will show sag or even tear.

(2) look at the appearance of the surface and the gloss of the surface. The best hollow plastic plate is made with the latest brand new. The color gloss is high and relatively uniform. Relatively dark materials have a shiny surface.
