MyCaseBuilder offers two options: Convoluted Foam and Solid (flat) Foam. Convoluted foam (also known as egg-crate foam) is the standard for lid foam, offering suitable protection while securing case items in place. It is also recommended for designs where items may protrude from the base into the case lid. Solid Foam is appropriate only for cases with very shallow lids (under 5/8"), or for designs where all items sit flush with the top surface of the base foam. Of course, the choice is yours. Lid foam is available when you are purchasing foam to fit a specific case (make/model).
