Introducing our Clear Ice Cube Maker Tray! This 2 - inch clear ice cube silicone mold can make 10 large crystal ice cubes, perfect for whiskey and cocktails. The oversized ice cubes, measuring 2 inches square, melt slowly, keeping your drinks cold for a longer time and causing less dilution. During the freezing process, the mold squeezes out air and particles, providing crystal - clear and tasteless ice. To use, simply fill the tray with water (water level about 5mm - 10mm from the top) and freeze for 18 - 24 hours. You can use purified, tap, or distilled water. If the ice isn't clear, try water with fewer minerals. The white foam box is an important insulation structure and should be placed in the freezer. It's a great gift for friends and looks elegant in any occasion, adding a touch of sophistication to your drinks. The product has dimensions of 11.42"L x 5.3"W x 5.7"H and comes in a package of 13.1 x 5.9 x 5.5 inches. With this ice cube maker, you can easily create a bar - like experience at home.
