A set of 2 molds avoid unmolding difficulties that allow you to release one ice cube at a time, thanks to its soft silicone design. Both trays are stackable for space saving in your freezer. You can make up to 9 ice cubes per tray, and with their convenient see-thru silicone lid, you can ice different things in each cube, such as pesto, sauce or even baby food. Once you try theses molds, we are sure you will never go back to your old plastic ones!
