Material Description:

Neodymium magnets are made from powerful rare earth metals. These 25/64" thick spheres are ultra-low profile, making them perfect for applications where a strong pull is needed without the bulk. They are the strongest commercially available permanent magnets for their size.

Note: Due to their sintered crystalline structure, these magnets are brittle. Handle with care to prevent them from snapping together and shattering. Always slide magnets apart rather than lifting.

Warnings and Safety Information:

• Keep away from children. Small magnets pose a choking hazard and can cause serious internal injury if swallowed.
• Avoid contact with pacemakers. Magnetic fields can interfere with medical device operation.
• Handle with caution. Magnets may snap together quickly; keep fingers clear and avoid impact.
• Not a toy. Designed for industrial, professional, and hobbyist use only.
• Thermal Sensitivity. Do not heat above 80°C (176°F) to prevent permanent loss of magnetic strength.
