All of our bowls have been certified and tested by a U.S. third-party lab as microwave-safe using food-grade FDA-approved polypropylene under normal use conditions.

To keep CaliBowls looking their best, avoid heating oil or heavily oiled foods at a high temperature for a long period as it may lead to stains or surface deterioration. If using tomato-based products, we suggest spraying the bowl with a nonstick cooking spray prior to heating.

If you have questions, please reference the FAQs or contact us.
