The 18" Round Dome Lid (EMI-380LP) by EMI Yoshi fits on all 18" Deli Mate, Party Tray, and Deli Max trays snugly and securely. The lid is ribbed on top with a textured edge for greater stacking ability, but still transparent for a clear view of the trays contents. 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. This model is taller than others, so you can guarantee safe and harmless transportation and storage regardless of your food presentation. Dome Lid. Finish: Clear. Size: 18". Shape: Round. Material: Plastic. Pack of 25.
