Discs are round or cylindricalNeos and generally are identified by the diameter first then the height of the disc. So a magnet labeled as 0.500” x 0.125” is a 0.500” diameter by 0.125” tall disc. Unless specified otherwise, these magnets are magnetized through the thickness.
Rings are round Neos that have a hole in the center. These Neodymium magnets that are available for sale will require three dimensions, an outside diameter, and an inside diameter and thickness. Unless specified otherwise, these magnets are magnetized through the thickness.
Neo blocks are rectangular or square with a variety of size options. These will require three measurements: length, width, and thickness. Unless specified otherwise, these magnets are magnetized through the thickness.
Neo Arcs have various shapes with a variety of size options, it is better to have drawings to determine the details.
Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.

As with everything, there are certain risks that people need to be aware of when working with these magnets. First of all size is an important part of this question. A small magnet such as a block is pretty harmless around your fingers. They will snap together easily but are not large enough to have fragments break off and fly around.
