These came all flattened in a stack and I was at first a bit clueless how to put them together. Thankfully someone in the Amazon reviews posted a little tutorial and I was up and running in no time. Really showcases the cupcakes. I had kind of hoped they would take jumbo cupcakes/muffins, and I think you could use the outer box for that and sit the jumbo muffin inside, but the separate inner stabilizing piece you actually stick the bottom of the cupcake in is really meant for a standard sized cupcake (to keep it from moving at all.) Super high quality, bakery level boxes. I don't think you will be disappointed.
