Size: 1/8 inch diameter x 1/2 inch thick cylinders. Nickel (Ni) Plated (silver-like shine) Grade: N48 - Extremely powerful magnetic material Pull Force is approximately 3.27 pounds per piece against a 1" steel plate
NEODYMIUM MAGNETS ARE NOT SAFE FOR CHILDREN
These cylinders are axially magnetized, so the strong North/south poles are in the center of the flat ends. That makes them easier to stack into a cylinder that to connect side by side.
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?
Honestly, I like to simply play with them, 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.
