Cylinder Magnet
Description
Wholesale Encapsulated Strong Cylinder Magnet – NdFeB + ABS
Cylinder magnet can be encased in heat-shrink tubing, providing extra protection. This heat-shrink wrap makes the magnets waterproof, shock-resistant, and oxidation-proof, ensuring they remain in optimal condition even in harsh environments. This added layer of protection increases their durability and reliability for long-term use in a wide range of applications.
