Very good quality plastic with cover for this egg organizer. Unfortunately, the design is for 14 eggs and the organizer no linger fits into the “egg compartment” on he door of of our refrigerator door. A minor inconvenience, and it really does not make sense. We are keeping it because the good quality plastic and the hassle of packaging this item for a return. The description and photo clearly show 14 eggs. My fault for not measuring prior to me order.
