LOVE! Love the colors, love the dishwasher safeness, love the fact that they are non stick, and love that my cupcake cook just as well in these as the paper cups that I no longer use, and I'm not having to go and buy paper cups and then have to throw them away. Wining!! The heart shape is adorable.Put your batter inside them and put in the oven. They rise as they should and they remove much better than any paper cup that I had previously always used.
