Tupperware Rainbow Cooker Saucepan 13 cm The steam generated inside the Rainbow Cooker hits the lid and turns into water droplets, creating a water seal, allowing you to cook with less water and seasonings without compromising the flavor of the ingredients. This cute pot is perfect for small servings or small dishes. Stored at home for a long time. The box and bag have some wrinkles and stains. Please consider this, and any initial scratches, before purchasing. Thank you.
