Information of Permanent Neodymium Block Magnet with Rubber Coating:
These amazing block magnets are protected by a layer of durable black rubber coating, which will effectively making them water-proof as well as incredibly resistant to damage. They can be slammed together many times without the risk of chipping or cracking like a normal magnet would.
We can also designed these powerful blocks with a countersunk hole on either side, making them some of the most versatile magnets we carry. Perfect for aquariums, marine environments, construction sites, outdoor applications and so much more! Super strong and super tough!
