Thank you for viewing. Set of 10 small, sealed food storage containers with valves, microwave-safe with the lid on. There are some minor scratches. This is a used item with a sense of use. Thank you for your understanding. Approximately 9.5cm wide x 12.5cm deep x 5.5cm high, approximately 230mL. These storage containers are made of engineering plastic, which has excellent heat and cold resistance. They are also highly transparent and look like glass. The lids have valves, so they can be used in the microwave with the lid on. (Heat resistance 140°C, cold resistance -20°C)
