Using this 7-piece Passage Dinnerware Set is a breeze. You can hold the plate, bowl, and mug with confidence thanks to the Cool Grip sidewalls, even when they're filled with hot food or drinks. When it's time to transport, just snap the cutlery together. You can also get creative and make a long spoon or spork by reversing a utensil and connecting the handles. To prevent spills, the steep sidewalls of the bowl and plate work great. As for maintenance, wash it with mild dish soap and warm water. Since it's made of EU food - grade glass - reinforced polypropylene, it's durable but still handle it gently to avoid any accidental drops. Don't use abrasive cleaners as they might damage the surface.
