They are amazingly powerful for their size and have innumerable uses. These block magnets are 1.57 inch (40mm) long, 0.40 inch (10mm) wide and 0.2 inch (5mm) thick. They are magnetized through the thickness. They are composed of neodymium iron boron magnetic material and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Maximum working temperature is 176 F (80 C). These Neodymium thin rectangular magnets provide an astonishing pull of 35 lbs and every magnet has a triple coating of nickel, copper and nickel again to prevent against corrosion. Our Neodymium magnets are commonly used in creative applications such as model making, theatre design, furniture making, exhibition displays and packaging. They also have many uses in engineering and manufacturing where small size and maximum strength are required. What's more, because of their resistance to demagnetisation they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets. Warning 1. Keep away from pacemakers. 2. Powerful magnets can hurt your fingers. 3. Not for children, parental supervision required. 4. All magnets may chip and shatter, but if used correctly can last a lifetime. 5. If damaged please dispose of completely. Shards are still magnetized and if swallowed can inflict serious damage. Review: Tiny but strong - Using these in resin to act as the closers for coffin shaped container, these are strong! Hopefully they work :D Review: Good product. - Bought these as I have a door insect mesh that clicks together in the middle. The magnets on the mesh are pathetic. A small breeze and the mesh opens. So I got these and now it stays together. Even in fairly good breeze. ## Features - ✅【Wide Range Application】 – These bar magnets provide you with countless possibilities and ideal for endless various purposes!
