These products are not safe for use by children who are less than three years of age, or older children who still mouth objects. If the child is not the recommended age of 6 years or older, consumers should stop using the magnetic sets and return the sets to Rose Art for a free replacement product suitable for young children under the age of 6 years. Consumers should be sure to keep all small magnets out of the hands of children who mouth objects, especially young children. For additional information, contact Rose Art at 800-779-7122.
