Dimensionally exact, within .001”, which is critical if you’re installing them in machined holes like I did. Super strong. Polarity is marked with a stripe, which I appreciate. And they have little plastic separators which helps get them apart from the stack. Fast shipping too. A+++.
Nice Magnets really strong
