These silicone ice cube trays from Kuuk are so cute! they are super flexible to help pop out the ice cubes when done. I remember that with older, plastic ice cube trays, I had to twist and bang them on the counter to get the ice cubes out. Definitely not the case with these! These are very high quality, not flimsy cheap ones. They are for more than just ice cubes made from water, too! You can freeze coffee cubes for iced coffee, or you could freeze Kool-Aid in them. That would be fun to mix and match flavors! These are very versatile!! You can get yours here. I received this product free in exchange for an honest review.
