Tupperware Ultra Pro 5.7 Lt • Produced from raw materials suitable for temperatures between -25°C and +230°C. It can be used in the freezer, refrigerator, microwave oven and regular oven. • Thanks to its rounded cover and body, heat is distributed equally everywhere. In this way, even in the microwave oven, the food cooks evenly on all parts. • The specially designed lid and handles allow the steam generated during cooking to escape, allowing your food to brown without drying out. • Ultra Pro Series is ideal for cooking in the oven at low temperatures and is suitable for roasts, fish and casseroles.
