Store more in less space with this Space-saving Square Container. It is part of a space-saving, food storage system to help maintain safe food-handling practices. Square container stores up to 25 percent more on a shelf than round containers in the same space. Break-resistant, clear polycarbonate offers easy visibility of contents & long life. Smooth surfaces allow easy cleaning. Dishwasher-safe container also features precise measurement gradations printed in red & blue. Temperature range is from negative 40 degrees Fahrenheit (negative 40 degrees Celsius) to 212 degrees Fahrenheit (100 degrees Celsius). A square, snap-on lid (sold separately) allows you to seal the containers to keep food fresh. With a lid, containers stack. Without a lid, they nest to save even more space. Container is made of FDA-compliant materials & assists in complying with HACCP guidelines.
