Wonder Bowls: One bowl that can do it all. Serve, store and heat. And this set comes with four different sizes. The answer to non-existent pantry space and overflowing dirty dishes? We think yes. Store & Transport: Say hellooo to leftovers. Each bowl in this set is paired with a leak-proof plastic lid that locks out excess air so contents stay fresh and easily transportable. And when you’re not storing food, they nest snugly for space-saving storage. Microwave Safe: Unlike steel that cannot be heated, these versatile bowls are made with durable ceramic. Each plastic lid features a vent, which when opened, releases pent up steam, preventing it from popping off. Narbonne Collection: Made from durable and glossy cream stoneware that’s safe for the dishwasher. The set includes 10.1, 16.9, 29, and 47 oz bowls. Each is embossed with a geometric pattern and finished with dark copper accents. The Kook Promise: We have carefully packaged each bowl with custom shipping protection to ensure it arrives in perfect condition.
