These amazing block magnets are protected by a layer of durable black plastic, effectively making them water-proof as well as incredibly resistant to damage. They can collide together many times without the risk of chipping or cracking like a normal magnet would. 

We've designed these powerful blocks with a hole that's countersunk on both sides, 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!
