NEODYMIUM MAGNETS ARE NOT SAFE FOR CHILDREN
These discs are axially magnetized, so the strong North/South poles are in the center of the flat sides.
That makes them easier to stack into a cylinder than to connect side by side.
*** CAUTION ****
These are very strong magnets! They can be very hard to pull apart. These magnets can fly together very quickly - watch your fingers.
The metal coating is durable, but ALL Neodymium magnets can chip or shatter. If used gently, these magnets can serve you for a lifetime.
These Neodymium Iron Boron magnets are also known as "Rare Earth" or NdFeB magnets. Neodymium magnets are simply incredible!
They are far more powerful than those old horseshoe magnets most of us grew up with.
What can these magnets be used for?
They are fun to play with, but these magnets have many practical uses as well. Use them on the fridge. Put them to work in the tool shed.
Use them as fasteners on cabinetry. They are great for science experiments. You are limited only by your imagination.
