Novelty & Funny Design: If you want to make your beverages appear cool and awesome, our 4 grids skull-shaped ice cube tray is an excellent alternative to those ordinary geometric ones. It can make your parties and festivals such as Halloween & Christmas fun and joyful, thus creeping your party up to the next level.

Safe Food-Grade Silicone: Since food-grade silicone is adopted as the material, facile and trustworthy, it's secure for you and your family to use in the kitchen, wherever in a refrigerator, microwave, or dishwasher. Furthermore, thanks to the flexibility and durability of the silicone, our ice ball makers are easy to release and won't crack or break like other plastic trays.

Excellent Sealing Effect: Both the lid and the base are made from flexible and durable silicone, so they can tightly fit upper and lower levers to avoid water leakage. Our 4-grid skull ice cube tray features an excellent sealing effect, ensuring to shape the liquids into iced skulls. Thus, your iced whiskey or cocktail can be chilled in style for a longer time.

Easy to Use: A small white funnel is equipped with our ice ball maker. It is trouble-free for you to pour water, whiskey, cocktail, or any other beverages into the tray. Cover the lid, pour water with the funnel, put ice molds in the refrigerator to freeze, and then the ice will pop out with a bit of push.
