OSORO's innovative character is to combine the quality of high-grade vitrified porcelain and its typical ivory-colored glossy skin with the function suitable for preserving food in the refrigerator or freezer and for cooking with steam oven or microwave. The simple, modular shape with its various elements can be stacked to save space, flexibly combined and closed with a multi-colored silicone O-Sealer or O-Connector so that food stays well sealed in it. OSORO can be universally used eliminating the need for our daily life.
