The 3-piece storage container set is made of transparent plastic and consists of boxes in three different sizes. Thanks to the cleverly designed white lids, the containers can be optimally stacked and stored in a space-saving manner. The sturdy material is food-safe, allowing for items such as cereal, pasta, and cookies to be stored without crumbs. To keep the storage containers looking nice for a long time, it is best to clean them by hand.
