The Flexible Measuring Cups allow you to form a spout anywhere along the flexible rims for precise pouring. The textured surfaces provide a secure grip, and two clear measurement windows allow you to view the contents. Made of translucent silicone, the Flexible Measuring Cups exhibit an innovative use of materials, a design principle celebrated in the Museum's collection. The large size may also be used as a mixing bowl. The cups nest for efficient storage. Microwave- and dishwasher-safe. Set of three. Capacity: one, two, and four cups.
