Don’t let these magnets fool you, they might be small but they still pack a punch. These Neodymium magnets have an incredible pulling force and are widely used in tight fitting places where larger objects cannot go. All magnets are manufactured using methods that protect against corrosion and prevents signed of wear and tear, further prolonging the shelf life. This is done through coating the magnet in four layers of Neodymium, Copper, Boron and Nickel, which also provide a smooth finish. Due to their small size they are commonly used by craft enthusiasts and model-makers alike. Additionally, these small magnets have properties useful to engineers, packagers and manufacturers due to their incredible mass to pull ratio.
