Rottay Ice Cube Trays

Not at all. The trays are dishwasher safe, and because they are made from a combination of flexible silicone and plastic, they are easy to rinse out by hand if you prefer.

Each set comes with a bonus funnel specifically designed to help you fill the sphere molds through the small opening on top without spilling water everywhere.

Yes, the molds feature bumping seals that lock the two halves together securely, ensuring the water stays contained and forms a complete, round sphere as it freezes.

The trays are designed with a balanced base to prevent leaning or tipping, so you can place them on any flat surface in your freezer without worrying about spills.

Both the square cubes and the round spheres measure approximately 2 inches, which is a substantial size that melts slowly and keeps your drinks cold without diluting them too quickly.

Because the molds use flexible silicone, you generally don't need to run them under water. Simply twist the tray slightly, and the ice should pop out easily.
