Great little magnets- these are thicker so getting your fingers on them to pry them off is a little easier than the thinner ones and these don't seem to chip or break as easily due to the thickness. These WILL work on the Wurkin Stiffs Polo Stays. Not certain is they pork on the regular Wurkin stiff collar stays but other reviews have previously stated that they do. They DO NOT work on the Maxton Men stainless steel collar stays.
ONE lot of 30 Magnets. Size: 5/16 inch diameter x 1/8 inch thick discs. Nickel (Ni) Plated (silver-like shine) Grade: N48 - Extremely powerful magnetic material Pull Force is approximately 3.8 pounds under ideal conditions. 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. The metal coating is durable, but ALL Neodymium magnets can chip or shatter. If used gently, these magnets can serve you for a lifetime.
