Excellent Quality Shelf.   Very sturdy and supplied with thick tempered glass.  Shelves are thick particle board covered in high gloss color core laminate. The shelves state that they are rated for 10lb capacity.  I can attest that they will easily handle at least three times that.Manufacturer could do a better job of packing the parts because one of my glass panels was scratched.  Based on previous experience and knowing that the item is very heavy/shipping ground service, I knew that Wayfair would quickly resolve any issues I may encounter.  They came through once again.
