These are best large ice cube trays I have ever used and I have tried a bunch. I found them on Amazon and they work perfect. The silicon works great to pop out the ice which is usually a down fall to these types of Ice trays. The best part is that have a sealed lid to keep them from spilling and are stackable which really helps for space. I personally use them for whiskey, but they can be used for all kinds of things like frozen soups, sauces, etc. The only cons that I can come up with is that these are priced more than most on Amazon but worth the few extra dollars. I highly recommend as it is worth the investment.
