This is actually way more than just a cake carrier; you can transport cake, cooled casserole, appetizers and more in safety and security. The key is the multi-function insert. The flat side of insert is perfect for transporting a 9" x 13" rectangular sheet cake and features a built in slicing guide. Fllip the insert over and you have a divided appetizer tray, perfect for vegetables, fruit, meats and cheese with a center space for dip. Remove the insert completely to create a recessed area for holding a cooled casserole or baking dish. Whatever you're carrying, there's a sturdy center-mounted handle for a secure grip, and four clips that lock the lid in place for transport. The lid collapses to half its normal height for storage and the insert nests inside. Overall dimensions are 15.63" x 19.75".
