Very nice quality - good view through the plastic. Some of the bases of the cupcakes didn't quite jam into the round spaces to hold them, but they still worked OK. Better than having them right smack against each other in a regular cake container that I had been using. Like that the trays can be reversed so that flat cakes could also be carried in the containers. Also discovered that two sets could be connected if you really wanted to have four levels stacked on top of each other. Kind of makes for heavy lifting if cupcakes are filled; but if you have something light that you want to carry all in one tower, it would work. We didn't try lifting the container by the handle - my cupcakes were just too heavy since their weight was doubled with the filling.
