This is a neat set of plastic storage containers made by Lock & Lock. They are built in a round, domed fashion. Perfect for storing cupcakes or muffins or things of that nature. They hold 10 oz and are approximately 3.5 inches tall and 4 inches in diameter.
Both containers are unused and in their original bags. I have quite a few of these, so feel free to look at my other listings and I can combine some for you if you're interested in a larger amount or variety of colors!
