The Square Enix eStore confirmed the Kingdom Hearts Keyblade silicone ice cube trays that let us make keys will be back in Japan starting on July 19, 2025. For 3,080円 (~$21), you get a pair of trays that allow you to make two Kingdom Key style ice cubes. Only the Japanese storefront showed a listing for the item, so it’s unknown if or when the US one will carry it.
Each of the Kingdom Hearts Keyblade silicone ice cube trays seems to let you make a Kingdom Key that is about six inches long. The mold as a whole is 165mm long. It’s soft, to make it easier to extract the ice cube when frozen. The example photos showed what it looks like empty, with an ice cube inside, when one ice cube is removed, and when an ice cube is in a glass. It seems identical to the design of the one first released back in December 2021 in Japan.
Here’s the full gallery of photos Square Enix shared.
When the original run for these ice cube trays appeared, it did show up worldwide. However, it did happen in July 2022, about seven months after the Japanese debut.
This is the second return of a piece of Kingdom Hearts merchandise inspired by the games. The Re:Chain of Memories playing cards are coming back. Those will show up in Japan in November 2025 again.
The Kingdom Hearts Keyblade silicone ice cube trays return to Japan on July 19, 2025, and it’s unknown when we might see them appear worldwide.
