Stronger and safer: Made of high-quality silicone and PP materials. BPA free, food grade LFGB certified! The 4 ice grid set uses better materials and design, making the ice grid more sturdy and durable. They can withstand long-term low-temperature storage without rupture. No longer worry about easy breakage. Don't waste your money! Start using ice cubes and bid farewell to those cheap disposable ice cubes! Easy de icing: The covered silicone ice tray is made of TPE material and has a widened bottom design, making it easy to release ice. The soft silicone material will not break after long-term freezing. Each flat cube compartment is separated from the other compartments, so you can easily push from the bottom. Without clumsy bending or twisting, removing ice cubes is no longer a daunting task! Lid lifter design: In order to facilitate the use of detachable lids, each lid is designed with two lid lifters. This user-friendly ice cube allows you to create perfectly sized ice cubes while preventing overflow and excess water from freezing, as well as preventing ice cubes from absorbing refrigerator odors. In addition, these easy to release trays can be easily and neatly stacked in the refrigerator without sticking. Each tray can produce 14 moderately sized cubes, totaling 56 (each with a capacity of 27 milliliters or 1 ounce). Easy to use and dishwasher washable: Fill the tray with water, cover it, and then slide it into the refrigerator. In addition to water, you can also fill a silicone ice tray with fruits, ice cream, soda, cocktails, whiskey, vodka, iced coffee, and wine to customize your favorite flavors. You just need to put them in the dishwasher after use.
