The 18″ Round Dome Lid (EMI-380L) by EMI Yoshi fits on all 18″ Deli Mate, Party Tray, and Deli Max trays snugly and securely. The lid is transparent on top for a clear view of the trays contents, and features a textured edge to add greater support for stacking ability. The lid is thick enough to last time and time again, but is also economical enough to be given away or thrown away depending upon your time and storage needs.
