The Southern Champion Tray 1010 cupcake insert is made of clay-coated kraft paperboard, which has a white exterior and a brown interior, and can be used inside a bakery box measuring 9" x 7" to securely hold six cupcakes (bakery box sold separately). Paperboard is thicker and more rigid than paper, is suitable for holding baked goods, and can be recycled or composted. The insert can be turned inside-out to display the brown side for use with a matching kraft paperboard bakery box. The lock corners facilitate assembly and enable the insert to be folded flat for storage or transport. The cupcake insert measures 8 7/8" x 6 7/8" x 3/4". Each cupcake hole measures 2 1/2" in diameter.
