    Warranty

    This magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions. Usage in environments with elevated temperatures, significant vibration, or intense opposing magnetic fields will render this warranty null and void. It is also not suitable for use outdoors or in areas with high humidity or salt content, unless additional protective insulation measures are implemented.

      Best magnet for its size

      Posted by George on Dec 21st 2021

      Just want to say Thank you for making the perfect magnet for me. It’s extremely strong and small enough to hide it somewhat. Shipping is fast too. Great product and a great company to order from. Customer for life!!!! George
