Please note that some of our products contain a magnetic closure and must be used with caution. Never allow magnets near a person with a pacemaker or similar medical aid; the magnetic fields of the magnet can affect the operation of such devices. If you have a pacemaker, consult your physician before using this product. The magnetic field may also damage magnetic media such as floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes, televisions, VCRs, computer monitors, and other CRT displays and devices. For this reason, never place magnets near electronic appliances.
