Material Description:

Neodymium magnets are made from powerful rare earth metals. These 1/32" thick blocks 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 ultra-thin profile, 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.
