The Wibimen mini ice cube trays are designed to produce tiny, 0.55-inch spherical ice, often referred to as "nugget" or "pebble" ice. This small geometry allows for a rapid freezing cycle, typically around two hours, and provides a high surface-area-to-volume ratio that chills drinks much faster than standard cubes. The set is built from food-grade polypropylene, offering a compact footprint for smaller freezers.
Specifications show that the trays use a press-fit lid that helps with stacking and organization. However, because the lid lacks a silicone gasket, it is most effective at preventing splashes rather than providing a total barrier against freezer odors over long periods. The rigid plastic construction requires a specific "twist" motion to release the spheres. To avoid stress on the material, it is helpful to let the tray sit briefly after removal from the freezer, as the plastic becomes more brittle at very low temperatures.
The included bin and scoop offer a convenient way to store and serve the mini spheres once they are harvested. While the small size is ideal for social-media-style beverage presentations and iced coffees, the process of filling and releasing these tiny spheres is more labor-intensive than using larger, flexible silicone molds. It is a specialized tool for those who specifically want the pebble-ice experience at home.
For a similar pebble-ice effect with a higher capacity per tray, the Fddbi 117-cell system might be a suitable alternative.
