Bought these to magnetize weapons for Adepta Sororita's Warhammer 40k Squads. These 3mm magnets fit the body but are too big for the hands - if you're trying to magnetize smaller parts I'd recommend a 2mm magnet instead. The magnets came in a small plastic box which makes them easy to use. keep and keep together. They seem strong enough and I haven't had any issues with them poorly connecting. They're a bit tricky to handle due to their size (and easily lost if you drop them). , but I suspect they'll get easier to use once you get used to them. The only thing I would change about these magnets is to add polarity markings, but overall they're pretty decent magnets based on my brief experience with them.
