This 10pk of cupcake boxes with windows and inserts, from Amazon, are new, in sealed package, made of cardboard, and easy to assemble. I assembled one of my other ones just so I could take pics. You have to assemble your own. The size of each box is 12 3/4"L x 9 3/4"W x 3 1/2"H, and will hold 12 standard size cupcakes or muffins. Thanks for looking. #104
