BPA free - Ice cube trays are made of food grade silicone which is soft and durable. You can fill the ice cube mold with fruits, ice cream, water, and wine to customize your favorite flavor. It is safe to touch food and drink directly and effective at freezing liquids like fruit juice, soup, and baby food. Classic shape and no deformation - Three classic shapes are designed to meet your needs: large cube shape: 5.6 x 1.6 inches (internal ice grid size: 1.5 x 1.5 inches), 6 ice cubes; large spherical shape: 6.0 x 1.6 inches (ice ball: 2 inches in diameter), 6 ice balls; honeycomb shape: 7.6 x 0.8 inches, 37 cells. The silicone ice cube tray is super flexible and durable and will not deform even when vigorously handled. Removable lids and not 100% sealed - To help prevent ice cubes from absorbing freezer odors and to keep them clean, removable lids are included. During the freezing process, water expands as it freezes, so the lids are not fully sealed to prevent potential bursting. Filling tip: fill to 75% to ensure ice cubes do not connect and spill. Easy to release and non-stick - Unlike rigid plastic ice cube trays, these flexible ice trays are made of durable silicone. The molds can be easily twisted or pushed from the bottom to release ice cubes quickly and effortlessly. Easy to clean - The silicone ice mold has a smooth surface for easy cleaning. It is recommended to wash and thoroughly dry the ice tray before first use. The ice tray with cover is also dishwasher safe for convenient cleaning.
