Nesting cups are a set of graduated cups that fit inside one another, typically made from plastic or silicone. They come in various sizes and colors, making them visually appealing for children. These cups are often used in playtime activities, helping kids learn about size, order, and measurement. In addition to being fun toys, nesting cups can also serve practical purposes in the kitchen. They can be used for measuring ingredients, serving snacks, or organizing small items. Their stackable design saves space, making them easy to store when not in use.
