Our ice trays and storage boxes are made of high-quality food-grade PP and PET materials, giving you peace of mind. These materials are durable, ensuring that your ice trays and storage boxes can withstand repeated use year after year while guaranteeing safety and quality. After filling the four trays with ice cubes, you can pour the ice cubes into the ice bucket we provided as a gift. The ice bucket has sufficient capacity to hold all the ice cubes in the tray, or even more, ensuring you always have ice cubes on hand! In addition to water, the tray can also hold juice, soda water and fruits to make refreshing drinks. Get creative with your family and friends and enjoy a refreshing drink in this warm month!
